It was a collection of silly quotes from IRC channels everywhere, many of which dated back to the 90s. It was rarely ever updated in the 2010s, but now, the URL no longer resolves.
Last capture was July 2023. https://web.archive.org/web/20230601000000*/bash.org
EDIT Someone archived all the quotes on the Internet Archive.
How is this different to Discord? You have huge, medium and small channels in both.
Most IRC servers I’ve been to had exactly one channel for the entire community/topic where everyone hung out. Either way, IRC is dead, it’s just fun how triggered some people get about it.
