What scripts (e.g. the serial-voting script) run at 3:00 UTC, as opposed to once every minute, few minutes, or 6 to 8 weeks?

This question was inspired by a specific thing I encountered: seven posts that I edited were removed at exactly 3:00 UTC, lowering my reputation by 14. While I did ask this question to figure out why that happened, it is not about that problem and only that problem, so please answer accordingly.

  • A link to one of the questions would help. Old downvoted questions get deleted after a while for instance.

  • @juergend I don't have links to any of those questions because they were deleted. You can look at my rep tab, though. It happened yesterday (12/27/13). Dec 28, 2013 at 2:13

    @Ryan In your specific case, seven posts you had previously edited got automatically deleted in the clean-up, and you lost the +2 reputation for each of those suggested edits.

This is probably not a complete list, but here are some of the things:

  • All tag-related processes. This includes recalculating tag scores, destroying tags that are abandoned, and awarding new tag badges.

  • Clean-up of low-quality and abandoned questions. See what qualifies for automatic deletion.

  • Automated reversals of voting fraud (serial voting).

  • Expiration of old close and reopen votes on questions.
