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.
No it’s not cause it’s easy to use, it’s cause Discord is controlled by a single company with various features behind paywalls and only one functional client app.
None of the paid features are necessary for effectively using it, they’re just “fun add-ons”
No API for third party apps is a genuine complaint though, it would be nice if there was at least some competitive push for them to have to strive to meet pushing them to be better
