The problem we have here is that he is trying to post the word S-t-i-t-s. Unfortunately our language filters are catching this and subbing asterisks instead. This is because the word contains the words t-i-t-s (hey, we're all adults here and we can discuss this right??) and that is the word that is flagging teh filters. I don't know if there is a fix for this or not, but I've asked my bosses at IB if there is anything we can do about it.
