flagged comments disappear instantly … what's going on?
Day before yesterday I met a strange situation, one user asking OP for accepting his answer in comment so I just went to flag his comment, While at the time of flagging the user already deleted his comment(as his answer was accepted) and flag process ignored.
I just want to know from StackOverflow that what we gonna do in such situation as it completely against StackOverflow rules.
Can't we stop user to do such tricks?
