The guild chat is tame for the most part, but their are expletives used quite a bit by some of the more low brow, less educated members (myself), but the profanity filter will likely catch it. If not, you can disable that, if they're not going to be looking for anything in Gchat. Same pretty much holds true for all chat areas, I guess...public chat in larger cities can definitely get sketchy at times.
