Well I figured sooner or later someone would ask.

Yes, there is a word filter.

It, however, is blank by default. I've added a few obvious ones, and need to add more. I've also added a few 're-mappings', so if you say certain bad words, rather than **** you'll get other terms. For instance, if you try to type s--- what you'll get is poop.

I'll probably be adding more words to the filter over time as need arises. Generally I'm relying on users to behave themselves, however, and use common sense about decency.

Yeah, we're doomed.
