Flashback to Neopets, which to this day censors basement, uncle, grape and skill(this one not everywhere though, can't recall), and the devs have the gall to say they have no plans in making the filter more precise when there are actual items on the site with those names that you can't write. The legendary Day the Filters Went Down is no excuse for people not being able to ask for certain items in the forums.
Auto censors do have a place for the swear words themselves(and just them, not words that happen to contain them) if the site is strictly PG and people can't help themselves, but if someone wants to get toxic, that won't stop them. Moderation from staff or the OP is the only way to control it.
