Lately there's been a lot of old questions popping up on the main website, with a status that reads modified X hours ago Community♦ 1.
On the profile for this account, it becomes clear that this is some sort of bot that keeps this website clean and managed and tries to bring attention to older questions, but isn't every hour a bit excessive on a website this calm?
There's also the concern that these questions may have been asked by users who have left this platform a long time ago without deleting their accounts, which would mean that new activity might ultimately miss the mark on having a positive impact on this website. But that's just speculation, of course.
