I still think its a good idea, but we probably need to just use a few, key words. For example, "anal" was censored, and suddenly my signature was completely screwed up. We just didn't take that into account, I suppose. We had an initial list of many words, but some are roots of others.
In retrospect, we probably should have thought of the Yoaka Amano case a bit more and thought about what words have roots that might prove problematic.
