There's nothing to see here, it's just that the amount of monthly reports coming in is much more than what the active mods can handle because most of the cases are handled manually, they're not bots I never expected them to handle all monthly reported cases, most of my last month reports were left unhandled I guess mod didn't pick it up
There are specific situations where leaving a report unhandled is actually the best course of action. Also, as suggested theymos releases this data at a certain point, if a user has reported a tonne of posts just before theymos collects his stats, then they're going to be unhandled. I'd say most of our reports get handled within a few hours, and the unhandled reports are probably much lower than this figure.
Isn't it true that unhandled cases aren't automatically revisited? Unless, if I'm correct, those cases are reported again.
