We introduced canned custom off topic close reasons for common reasons to ease community moderation.
Increasingly we observe people to choose such a canned reason for questions where this reason is only marginally correct. This alone would not matter much, as we need 5 close votes to put a question on hold.
Sadly we do have enough robot reviewers that blindly follow the first vote. This leads to closing questions with a wrong reason. It does not help anybody to do so, even less if is accompanied with closing without comment (that occurs often too).
This is a network wide issue which led to the introduction of review audits to be able to ban such robo-reviewers.
We are a small site, still in beta, hence probably won't need such audits but moderating robot-reviews is not easy. We may not detect robot reviews easily and we do not want to ban the wrong people from reviewing.
Any suggestions on how we should deal with wrong close reasons and robot reviews are welcome.
