I'm against heavy handed regulation because it pushes people into more dangerous spaces, if you're a teenager or unID'd adult who can't access real porn sites do you decide not to look at boobs or do you seek out unregulated communities on places like discord?
Would you like your kid seeing generic regulated porn or seeing the kinds of things people can't post on regulated porn sites? Plus not only is there the fact that the content on underground sites is by their nature the stuff not allowed on regulated sites but also do you want your kid taking to the creeps that hang out in porn sharing groups on discord?
