Hi, I'm wondering if it's allowed to register XXX domains for non-adult websites. Not planning on registering yet (not possible right now anyway, AFAIK), but I'd definately get one in future.
I think its possible. But you will waste your time. Many ISP will blocked .xxx domain, and your site will no visitor. And please note, the .xxx domain is very expensive.
I would not do it, regardless of what your site is about with a .xxx everyone will assume its adult including Google
