| name: Spam comment guard | |
| # Activity-farming bots post short emoji-padded template comments on whatever | |
| # issue is currently active. They are cheap to spot structurally: a recently | |
| # registered account with no history here, no followers, and a pile of forked | |
| # repos, posting a sub-50 character comment with emoji and no code/link/log. | |
| # Every signal must fire — on 7604 replayed comments that caught all 83 known | |
| # spam posts with no false positive. Loosening any one of them reintroduces | |
| # real users ("点赞", "同样的问题", a 2020 account posting "感谢各位❤"). | |
