It’s worth mentioning that we have a “watched words” feature in the works for 1.9 (current beta) where based on the presence of a word in a post:
- post could be auto-blocked
- post could be auto-flagged
- post could require mod approval
- word could be censored
(pick one, obviously)
Mostly this is because I tend to agree that the presence of certain words in a discussion is practically a guarantee that things are going wrong in that discussion. We could debate what those words are, and we absolutely should, but… I am confident we can all come up with a few words that we know (and have personally experienced) cause discussions to have a very high probability of going wrong.
