The monk silenced you must have been on the Power Users list. Generally, these people are are there because they are trusted not to abuse this authority. To date, I believe I've only used this ability twice. Both times I gave warning to the offending party that I was going to silence them if they didn't watch their language. Personally, I am very tolerant of offensive language. I have only stepped in when profanity starts getting directed at another user in anger.
