You've been getting PRs? All I've ever seen is "can you assign this issue you me" spam and then disappear. I was nice to them for years but now I just delete the comment and block the users.

Yeah, the "can you assign the issue to me" is the most common. I don't even understand where it came from - does anyone ever actually formally assign issues to anyone?

But they absolutely also create PRs even if you say "don't create a PR. You don't know what you're talking about"
