The ID checks will only make things worse. Like 4 free “tube” sites based in America and that are trying to be mainstream and ad-supported (Pornhub and ????) comply with Louisiana’s current ID check law while the 5,000 sites based anywhere else on Earth don’t give a shit. Most probably don’t even filter for CSAM.
Half the internet is porn. Reddit has porn. There’s a Lemmy instance for NSFW stuff. To imagine they’re going to stop teens from finding smut because the “reputable” site checks ID is just willful naivety.
Also, I realize the goal of the Texas law is to label anything GLBT+ as “porn.” I’m not the naive one in this case. But the arguments in the case aren’t about the hidden agenda of conservatives.
Once you get the big players with heavy wallets out of the way, then you can go after search engines that list it. Search engines probably don't have enough motive to fight it, and the big players already packed their bags. Once it's no longer on Google/Bing it may as well not exist for the vast majority of people.
There was an article about one of the masterminds behind these laws that got secretly recorded and he basically confirmed what I just said. ID laws are the start.
