I've noticed a few questions disappear without a trace from the main site. Not that it's a big loss (I voted to close them) but there is no trace left of their existence. I have access to the moderator tools, which is supposed to show closed & deleted questions but they're not listed there either.
I'm curious as to what's going on -- can anyone shed some light on this?
UPDATE:
I'm not suggesting that something sinister is going on or that there are bugs in the system, I'm genuinely curious if there are cases where this could happen. Like a user deleting/retracting their own question?
I'd post links to the questions, but the point is that I can't find them at all.
