Not anymore in germany. We can't even see the dev pages of nsfw developers on Steam anymore (Web version and client version). It's rediculous because the only reason that's been given is that underaged people might be able to buy this stuff (while every way of online banking is available for adults only anyways).
Currently some courts in our country are seriously working on deciding that our ISPs have to block every major porn site. I can't even find words for how backwards societies are moving in some aspects.
