IRC was also quite dangerous for the uninitiated, you could take down a person from the other side of the country (world if lag didn't kill you first) before they knew what was happening, it was personal hacking at it's easiest.
Many of today's script junkies cut their teeth hacking IRC users, but it's the ones who were stopped in their tracks by someone who was smarter than them that always made me laugh. Most of my old channels from 10 years ago still have 3 or 4 of the old school l33t mob sitting there with bots in channel, only talking to tell the few remaining souls who wander into channel how failure to keep to the rules will result in attacks from bots.
IRC was fun for the wannabe hackers alone.
