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.
I don’t think any open source platform brings together the kind of functionality Discord currently has, but I’m open to being corrected on that. If there was a better platform doing what Discord does then that would be great to use. Having had to switch from different platforms for video calling for various reasons I get what you mean.
