I once got muted for 4400 hrs (true story) for vulching the same guy 5 times. Had no idea what 200 was at the time. He may have been a Mod, I really don't know. Talked to Skuzzy who said I may have been muted for my callsign at the time. (won't say what it was for fear of a vacation from the BBs)
I was also given a warning for using the F-bomb in a PM chat with a squaddie. I don't type any kind of cuss words anymore. If I feel the need I try and phrase it another way. i.e. WTF, WTH, oh crab apples, etc.
As far as 200 goes I rarely tune in at all anymore.
