There are a lot of copy paste accounts out there, may it be copied from another website or steem user, that should be flagged. But unfortunately like you say it's first costly and most likely causing a personal flag war on top of it.

Minnows are scared of it due to those points, especially whenever it comes to abuse through whales. With great power comes great responsibility and I hope that at least some more whales will take their important role seriously on the steem blockchain.
