South Carolina lawmakers are advancing protective legislation in direct response to growing evidence that Meta and YouTube have designed their platforms to be addictive to young users. Following a March 25, 2026 jury verdict that found Meta and Google’s YouTube negligent in a social media addiction case—awarding $6 million in damages to a 20-year-old plaintiff—South Carolina’s legislature has moved swiftly to strengthen state protections. The state passed HB 3431 (Social Media Regulation Act) effective February 5, 2026, and recently advanced HB 4591 (Stop Harm from Addictive Social Media Act) through the Judiciary Committee on March 26, 2026, signaling bipartisan concern about the harms these platforms pose to young people. This article examines what the historic verdict means, how South Carolina is responding legislatively, what consumers need to know about pending cases, and what changes might come for social media companies.

What Did the California Jury Decide About Meta and YouTube Addiction?
On March 25, 2026, a California jury returned a landmark verdict finding both Meta Platforms and Google’s YouTube negligent for designing features that addict young users to their platforms. The case involved KGM (Kaley), a 20-year-old from Chico, California, who began using YouTube at age 6 and Instagram at age 11—during critical developmental years. The jury awarded $6 million in total damages: $3 million in compensatory damages and $3 million in punitive damages.
Notably, Meta was held liable for 70 percent of the damages, reflecting its particular responsibility for addictive design in Instagram and its broader Meta ecosystem. This verdict carries enormous significance beyond the individual case. It affects approximately 2,000 pending lawsuits against these platforms, establishing a legal precedent that juries will hold social media companies accountable for negligence in designing addictive features. For the first time in a major lawsuit, a jury has concluded that Meta and YouTube knowingly created mechanisms—infinite scroll, algorithmic feeds, notification systems—that exploit young people’s developing brains to maximize engagement, regardless of harm.
How Has South Carolina’s Legislature Responded to Social Media Harm Evidence?
South Carolina lawmakers have not waited for additional verdicts to act. The state enacted HB 3431, the Social Media Regulation Act, which became effective on February 5, 2026. This legislation establishes baseline protections for minors on social media platforms, requiring companies to implement age verification, restrict data collection on users under 18, and limit algorithmic personalization for young users.
The law represents South Carolina’s position that the state cannot rely on voluntary industry self-regulation while young people suffer documented harms including increased anxiety, depression, and addiction behaviors. Building on this foundation, the South Carolina legislature advanced HB 4591, the Stop Harm from Addictive Social Media (SHASM) Act, which received a favorable report from the Judiciary Committee on March 26, 2026—just one day after the California jury verdict. This bill is more aggressive, targeting the specific design mechanisms identified in litigation as addictive: infinite scroll, autoplay features, and algorithmically-amplified content feeds. However, if Meta and YouTube challenge these laws in federal court (as they have challenged similar laws in other states), South Carolina may face litigation costs and prolonged implementation delays before the protections take effect.
What Do These Laws Mean for Social Media Users in South Carolina?
For South Carolina residents, particularly parents and young people, these laws establish enforceable rights that did not exist before. When HB 3431 and HB 4591 are fully implemented, Meta and YouTube will be required to provide parents with monitoring tools, restrict targeted advertising to minors, and disable addictive features by default for users under 18. Unlike voluntary “parental controls” that companies market but rarely enforce, these are state-mandated requirements with penalties for non-compliance.
The laws also establish that platforms cannot use the excuse that a feature is “free to use” to avoid responsibility for designing it to be addictive. A practical example: under HB 4591, Instagram would be prohibited from using its infinite scroll feature with minor users—a feature the company has repeatedly admitted is designed to maximize time spent on the app. Instead, Instagram would need to show minors a defined number of posts per session before requiring them to take a break. This applies to all platforms operating in South Carolina, not just Meta, creating competitive pressure on TikTok, YouTube, and emerging platforms to adopt similar safeguards or lose South Carolina users.
What Are the Differences Between South Carolina’s Approach and Federal Regulation?
South Carolina is not waiting for federal legislation, which has stalled in Congress for years despite bipartisan concern. The state is taking a direct regulatory approach, similar to how California has pioneered privacy and data protection laws that other states then adopt.
This creates a patchwork risk for social media companies: they must now comply with different standards in California, South Carolina, Arkansas, Tennessee, and other states that have passed social media regulation bills. However, if you are not a South Carolina resident, you should know that these protections may not apply to you unless your state passes similar legislation. This creates an incentive problem where tech companies may simply comply with the strictest state law (likely California) for all users, or where they may provide degraded experiences in regulated states while keeping addictive features active elsewhere.
How Does the California Verdict Strengthen These South Carolina Laws?
The March 25 jury verdict provides powerful evidence that South Carolina’s legislature is not overreaching or regulating based on speculation—it is responding to documented corporate negligence. When HB 4591 faces legal challenges (which are likely), South Carolina’s attorneys can point to the California case and say: “A jury of ordinary citizens heard the evidence and concluded Meta and YouTube designed addictive products that harm young people. Our state has the constitutional authority to protect its residents from such harms.” This shifts the burden of proof: rather than South Carolina needing to prove harm, the tech companies must explain why a jury verdict establishing negligence should not inform state regulation.
A limitation to note: the verdict came from a civil negligence case in California under California law, not from a regulatory or criminal proceeding. While it establishes that juries believe Meta and YouTube acted negligently, it does not constitute a finding that the companies violated South Carolina law specifically. However, the precedent is extremely valuable because it demonstrates that the business model—designing for addiction—is not a gray area of corporate behavior; it is conduct a jury deemed reckless.
What Should South Carolina Residents Know About the Pending Lawsuits?
The California verdict affects approximately 2,000 pending lawsuits against Meta and YouTube. If you are a South Carolina resident who believes you or a family member was harmed by social media addiction, you may be part of a pending lawsuit or eligible to join one. Many of these cases are being consolidated in multi-district litigation (MDL) in federal court, which allows individual cases to proceed together while sharing discovery and evidence.
The California verdict does not automatically settle the pending cases, but it strengthens the negotiating position of plaintiffs’ attorneys, who can now argue to judges that a jury has already found liability. The damages available in pending lawsuits may include compensation for documented harms such as anxiety, depression, sleep disruption, and academic damage. If you believe you have such claims, consult with an attorney in your state to understand whether you are part of an existing litigation group and what your timeline and options are. Many of these cases offer free consultations, and attorneys typically work on a contingency fee basis, meaning you pay nothing unless you receive compensation.
What Changes Might Come for Social Media Companies Going Forward?
The March 2026 verdict and South Carolina’s legislative response signal that the era of social media platforms operating without accountability for addictive design is ending. Meta and YouTube face pressure on multiple fronts: state regulation through bills like HB 4591, federal litigation through the 2,000 pending cases, and growing federal scrutiny from Congress and the FTC. In response, these companies may redesign their platforms to remove infinite scroll, disable algorithmic feeds for minors, or implement friction into their user interfaces—all changes that will reduce engagement metrics but may reduce liability exposure.
For users and families, this means the next 18 to 24 months will likely see significant changes to how social media platforms operate, at least in regulated states. Whether these changes extend nationally depends on whether the federal government acts or whether additional state regulations gain momentum. The March verdict has also emboldened other plaintiffs and plaintiffs’ attorneys to pursue similar litigation, increasing the pressure on Meta, YouTube, and other platforms to settle pending cases or face additional jury verdicts.
Conclusion
South Carolina’s legislative response to the Meta and YouTube addiction verdict reflects a broader shift in how society views social media company responsibility. The state has enacted HB 3431 and advanced HB 4591 to establish concrete protections for young people against addictive design, using the California jury verdict as evidence that these protections are necessary. The verdict itself—awarding $6 million and establishing Meta and YouTube’s negligence—affects 2,000 pending lawsuits and provides a roadmap for how juries evaluate claims of intentional design for addiction.
If you are a South Carolina resident concerned about social media’s impact on your family, understand that new legal protections are coming and that existing litigation may provide compensation for documented harms. Consult with an attorney about whether you or your family members are eligible for the pending cases, and monitor your state’s implementation of HB 3431 and HB 4591 to understand what new platform restrictions will apply. The verdict marks a turning point: social media companies can no longer claim that addiction is an unintended byproduct of their platforms. Juries, regulators, and voters increasingly view addictive design as a form of corporate negligence.
Frequently Asked Questions
Does the California verdict automatically affect my case if I’m in South Carolina?
The verdict is persuasive authority but not binding on South Carolina courts. However, it strengthens pending South Carolina cases by establishing that juries will hold platforms liable for addictive design.
When do HB 3431 and HB 4591 actually take effect?
HB 3431 became effective February 5, 2026. HB 4591 passed the Judiciary Committee on March 26, 2026, and must pass full legislative votes; the effective date depends on final passage and any gubernatorial signature timeline.
Can I sue Meta or YouTube separately if I’m already part of a pending case?
Generally, once you are part of a consolidated lawsuit (MDL), you cannot file separately. However, if you are not yet part of litigation, you should consult an attorney immediately to protect your rights.
What if I’m not in South Carolina—do these laws protect me?
These state laws only apply in South Carolina. However, other states have passed similar legislation, and the precedent from the California verdict may encourage your state’s legislature to act.
What counts as “addictive design” under HB 4591?
The bill specifically targets infinite scroll, autoplay features, and algorithmically-amplified content feeds—features Meta and YouTube use to maximize time spent on their platforms.
How much compensation could I receive if I’m part of a pending case?
Compensation varies based on documented harm (anxiety, depression, academic impact) and the strength of individual evidence. The California plaintiff received $6 million, but that is an exceptional case; most settlements provide more modest compensation per plaintiff.
