TL;DR Most people are against a age verification where you would input your personal ID or credit card. Adding a popup would be nice though (if it doesn't already exist)

Thinking about all the included responsibilities, legislation, etc. gives me headache so I will not bother setting up a NSFW instance, from which thought the question originated... Thats propably why there isn't a good one right now

The thing is, that it is only required if the company is located in Germany. Thats why pornhub, a company run by Germans (afaik) does not have to do it... It was in the news multiple times, when the government tried to remove that condition so all porn sites accessed from Germany have to verify the age of the German visitors.

But the prohibition of alcohol and tabacco from kids have nothing to do with saving other people from the effect these kids under the unfluence could have. The age limit is there to save kids from getting used to these substances in their early developement, so they don't become addicted to them. Or am I missing something?

That would be an interesting approach, but browsers are easily switched (to a "jailbroken" one) and I wouldn't trust windows with such information... Linux would be fine, but I guess the linux community would at least be torn on this one (though I might ofc be wrong)

I did not find something about that in their docs... Do you have a link for that?

Something like this is exactly what I meant

I dont know about that one. Following this logic why is it forbidden to sell alcohol and tabacco to minors or why are so many drugs illegal like everywhere, when good parenting prevents the use of these by minors? Of course this comparision is far fetched, but I dont think that the problem is solved by just filtering the internet access of minors.

According to this wikipedia article it is mandated for pornography in Germany and the UK. Interestingly enough some alcohol companies in the US also try to verify their users age to ship them alcohol... So yeah a pretty isolated problem I guess

Maybe some other countries included, but yes propably. But imo it would be beneficial for everyone, but I get that people disagree with that

No sadly I don't. I guess for most plattforms its just so much easier to not host the server in Germany/EU...

And this process does not necessarily have to use ypu personal ID

That is not necessary for age verification. You just have to go through a working verification process and then you just get the checkmark in the database. most sites that really verify your age use credit cards for that, which are of course sub par, because children can just take the cards from their parents, but it is better than nothing

And what is with instances that federate with an nsfw instance. Its users are not asked for verification. I was just curious if ther will be a system that is doing something to prevent minors from seeing porn

Nope I meant real verification. Pornhub doesn't require it, because the server and the company are not stated in Germany. Imo all porn site should have real verification instead of the "I am 18 or older" popup, that literally does nothing to prevemt minors from seeing porn.
