What on earth makes you think that denouncing a bot PR with stronger language would deter it? The bot does not and cannot care.
If that worked, then there would be an epidemic of phone scammers or email phishers having epiphanies and changing careers when their victims reply with (well deserved) angry screeds.
I didn't mean the "fuck off" part to be quite verbatim... this ghostty PR[0] is a good example of how this stuff should be handled. Notably: there's no attempt to review or provide feedback--it's instantly recognized as a slop PR--and it's an instant ban from repo.
This is the level of response these PRs deserve. What people shouldn't be doing is treating these as good-faith requests and trying to provide feedback or asking them to refactor, like they're mentoring a junior dev. It'll just fall on deaf ears.
