I've noticed two things this morning that appear to be related:
- There have been more than the usual number of "why did I lose reputation" questions here on Meta Stack Overflow, all apparently related to deleted questions. Indeed, on several of the sites in the network I have seen a lot of changes to my reputation related to items being deleted. Much more than usual.
- On the sites where I have access to the 10k tools, I see a large number of questions deleted by Community ♦ at around midnight EDT (-0400 UTC). From the ones I looked at they're all questions with 0 or lower score, no positively upvoted answers, and were closed back in August and September. (Some closures may be older than that, but the 10k "recently deleted" tool only goes back so far.)
So, do we have some new tweaks to the auto-delete mechanism(s)/criteria, or was a cron job not running and repaired yesterday?
