Controversies

Anonymity for minors and enforceability  
Many people have stated that privacy for minors, mainly minors a part of the LGBTQ community, may be less available, and many people don't think that the bill is enforceable since the law is based on cyber-usage, and since companies like TikTok aren't based in the United States, they can't enforce the regulation on those companies.
