I've no idea why, but I just spent too long immersing myself in RoundSparrow drama: all his comments on GitHub are now marked as Abuse, and the account at lemmy.ml is now banned (I realise it's not his only one).
I can, in some ways, relate to the feeling of being gaslighted when submitting a PR to someone else's GitHub project. Either being told that the issue isn't actually an issue, or - more commonly in my experience - being told that the fix has already been implemented on some private branch by a main developer (which then never sees the light of day).
I guess the gist is: Lemmy relies on auto-generated SQL that isn't efficiently handled (maybe).
That last PR is a bit sad to read. Was all going well until the other Project Lead stepped in, and then chaos.
If it's still there, the newest post in !fediverse@lemmy.ml (about blahaj) is not massively dissimilar (in essentially being about Autistic people struggling with online communications)
