And what happens 5 minutes later after all those unregistered users looking to optimize their transfers have finished downloading one of the cracks or key generators for mIRC? I realise I'm being the 'put-down guy' for filesharing prevention (on 2 threads now), but lets be realistic. It's really not practical or possible for mIRC to 'decide' what can and cannot be sent - short of removing the DCC send ability totally. Even then it would be scripted back in within a day or two and nothing has changed. I simply don't think that it's the IRC client's place to police the files sent via DCC. If anyone has the ability and, to some extent, the responsibility to limit or prevent filesharing it's the IRC servers and their staff.
