This question already has an answer here:
This post was flagged by the system as vandalism, because the user had just deleted five of his old junk answers (need 10K rep to see):
Notice that these are all zero-voted and 3 of the 5 questions are closed!
So, I flagged this: "Not vandalism. These are all zero-voted answers on Q's that were either closed or have better answers." I've flagged this way probably a dozen times, and it's always been found "helpful".
This time, the flag was declined -- meaning that the deletions were vandalism! (The decline-message was the standard "a moderator reviewed your flag, but found no evidence to support it".)
Yet, all 5 answers remain deleted. Shouldn't they be restored if it was vandalism to delete them?
So, was this vandalism?
Was the mod having an off moment?
