The AntiSwearBot is a bot that either deletes, flags, or ignores offending words or messages that have offending words in them. The bot has a good deal of customizability, such as the ability to turn on a warning system, and choose how many warnings it takes to kick a user. Messages are censored at certain degrees, chosen by administrators depending on what they are looking for. Specific commands can be found using -help.
