A blacklist for words is such a lazy solution, lol.

I remember back in the old days of Westwood, their online games had a strict list of bannable words, and it was always fun to bait people into using them with seemingly innocent questions. "Hey, I'm doing a history report on WWII, does anyone know the name of the leader of the SS? Himm-something?"

Some poor schmuck: "You mean Himmler?"
