As long as the content isn't underaged or copyrighted, Dreamhost is pretty cool. They're one of a couple of hosts out there that are okay with hosting actual (real live, 2257 requiring visual representations of the old in out) porn as long as it's not underaged or otherwise illegal. I can't say for sure that they'd be cool with chan, if you've got that, but in my experience w/ them, as long as you're not posting movies/ shows, they're okay. And pretty much any provider out there's going to TOS you for that.

That being said, if you're looking for another adult content friendly host, I've heard good things about Lunar pages.
