I find Courel passable. You get the occasional arse, but normally the community, at least publicly, such as in Mor Dhona shout chat (or whereever that will end up post HW) is pretty good. My FC is full of polite, adult people, so that is a plus. That said, it all depends on what you would call "perverted, disgusting". Sometimes profanity happens, or in my FC, crude humor, but its kept to a minimum.
