you know how you fix that problem billy

You send them a letter telling them "I seem to be unable to read your bill, untill you send me more info on how i can resolve this problem I wont be able to do so, so expect delays in recieving your bill payment" then put a small note at the bottom, saying " I beleive this issue may be connected to your blocking of IRC DCC sessions " if u dont think so well please send me your reasoning in triplicate so i can not read them either "

Try a SSL connection, if the irc traffic is encrypted one would logic that they cant detect the strings there using to trip the disconenct on.
