Github suggests reviewers to PR authors based on who's been modifying nearby code recently (ok, I don't know whether that's a general policy, but it happens to me all of the time). And for the past year or so I have been getting tagged to review more and more AI slop from newcomers to the project that we chose to maintain in public. I just immediately nope out of all reviews now if I don't recognize the submitter, because I don't scale enough to be the only actual human involved with understanding the code coming at me. This sucks for the newcomers who actually wrote the patch themselves, but I can't always tell. Put some misspellings in your comments and I'm actually more likely to review it!
