One problem is that GH gives you no way to disable PRs. And even if you write in BIG BOLD LETTERS that PRs should be on Codeberg not GH, people get upset and make a fuss over their "ignored" PRs and it ends up making unnecessary headaches for you over and over.

Can do it the @torvalds/linux way and have a bot auto-answer/close PRs. And, to be honest, probably is better to ignore people making a fuss over PRs.

You can ignore them yourself, but people will get annoyed, take to social media, post "this project ignores PRs" "dead project" "they're not inclusive" etc. without context, and those things can gain momentum out of nowhere and have real consequences. And there will goalpost-shifting again, from "just mirror to GH" to "just accept PRs on GH too, why are they being so obstinate" and then further along.

The Linux kernel is unlikely to get those and can survive that even if it does, but your average FOSS project can be severely damaged in terms of reputation, contribution, usage, etc., by this kind of stuff, even if you want to dismiss it as just "social media fluttering". Easier and safer just to keep things clean and clearly at one place.

This seems workable to me. Github rose to prominence on the back of oss. What oss giveth oss can take away.

Glad to see codebrg getting recognition. The age of relying on for profit corps for our digital commons needs to end.
