Discord has allegedly started to ban users who use unofficial (read: non-malware) clients: https://github.com/Bios-Marcel/cordless#i-am-closing-down-the-cordless-project. I'm sure that I am preaching to the choir here, but communities for open-source projects should NOT be hosted on Discord and this is yet another example of why.
It frustrates me that several projects that I'd consider contributing to are run solely through Discord.
