This explains a lot! mIRC's file shariing abilities are about as technically advanced as the 20 year old FTP protocol, and have absolutely NO facets of any current P2P software, but hey.. it's ELITE!

Downloading off IRC (in the sense of xdcc/fserves or whatever) is probably the LEAST SAFEST WAY TO DOWNLOAD. Read the *$%&'ing topics of such channels, where do you think XDCCBOT-12125421 comes from?
