In my opinion, maintainers need to more actively block inconsiderate people. One thing Github should do is provide moderators ability to import a list of user accounts to block right from the gate. This way, communities can curate filters of accounts to be blocked like uBlock lists.

Rude and inconsiderate people need feel the pain of being actively blocked everywhere and not able to get anywhere forward with any of their requests. This can at least help OSS maintainers and developers get a little bit of mental sanity back
