Discord is great for providing a community chatroom for both voice and text. It started, and still is, as the combination of IRC and Teamspeak/Ventrilo, now just with more bloat and memes. That people are trying to use the “IRCTeamspeak” as the entire information platform for their open source project is just mental, as it puts everything hidden behind a login requirement, unindexable and unsearchable on any search engine in an ever-changing stream of unrelated discussion.
Stick your bug reports and issues in a Github/Gitlab etc tracker, your information into a Wiki, and set up a forum. The discord can exist alongside these, but it cannot properly replace any of them.
