Someone was editing that wiki, but to be clear Pissnet is not affiliated with Freenode, though it was born from its collapse. It is a small but active community, and has a couple hundred servers.

It's very hard to explain, but it is a real network that currently operates as an anarchic sandbox for doing weird things with IRC software/protocols and just generally goofing around.

Pretty much every single active user is a netadmin. It's the network where you register a nick by linking your own server.
