QuakeNet
The worst run IRC network about? Quite possibly.
It works quite nicely, although there is no way of registering your username, so you have to pay for a bot or some kind to store it while your offline.
And if your bot disconnects then your channel is often free for the taking. This though is against the rules. The feds are always at hand to help you, and remove any troublesome people.
Yeah... right. I spent over an hour in their channel asking for help, none of the 22 there could be arsed to help me. I won't get a chance to speak to them until tomorrow night, and by which time they will probably say, oooo it's too late.
