I actually just checked after seeing this post, no ID requirement popping up in Tennessee for whatever reason. I also realized I don't believe I had ever typed pornhub.com into a browser before until now. If somehow i had ever been there it was from search engine results I guess, never knew they had a main page.
Tfgames.site (not a commercial site, but a database of adult videogames involving physical transformations) stopped allowing access to IPs geolocated to at least some states due to similar laws, ID or no.
As of today, Florida, Tennessee, and South Carolina join the list of 17 states that can’t access some of the most popular porn sites on the internet, because of regressive laws that claim to protect children but restrict adults’ use of the internet, instead.
