mIRC has a built-in DCC server, so it's a feature in mIRC that people have a right to ask about. If you don't want to help with that for whatever reason then of course you don't have to, but if that's the case then don't respond. Nobody wants or needs to know your wild guesses about the percentage of legal files being served via DCC, nor do they care about your moral stances about random features in mIRC. This forum has a general policy about filesharing and illegal downloads, but there's nothing in any of these posts that suggests anything illicit is going on here and the problem itself is nothing to do with the number of files being sent or what they contain.
