If the profanity is very bad the comment is usually pulled. Also, FR has a rule against using profanity, DU does not. The amount of profanity at DU is about 1000 times over and above anything I have ever seen on FR. If you don't believe that then go to DU and check it out. They use the F word as an adjective, verb, pronoun, noun and adverb.
I completely agree. Profanity is not tolerated at FR. It does however get missed sometimes and that was my only point. Someone said that we don’t have profanity on FR and that simply isn’t true.
