Ask HN: Why is it not possible to report hacked social media accounts?

More than a few times in the past, I’ve seen accounts of friends hacked, usually facebook and instagram. In one recent case, it’s obviously a russian bot account because photos of Alyona Arshinova started appearing on the account. In a few other cases, it seemed to be possibly a personal account in the middle east after some time.

The friends in question had mostly given up on the accounts before they were hacked, but there has never been an option to report a hacked account on Facebook, Instagram, or if I recall, twitter either. Is this some kind of conscious decision?
