As far as I can remember. There was a pro LGBT tweet that some people didn't like. And the moderator decided to blanket ban everyone who disagreed with the tweet. Some of the banned people had reasonable objections like: regardless if they agree with something or not politics and OS should be separated, and were still banned, including on GitHub. Others had objections also shared with the Godot founder and were still banned. There were some other things also but can't remember the details.
