I guess many are doing this kind of aka 'abuse'.
If we list them down and keep flagging them, it would be a waste of time and money or maybe not.
I guess Steemit, Inc., the witnesses, developers and investors are already have plans how to get rid of these problems.
An upgrade or a hard fork on the steem blockchain maybe would be a solution, I don't know.
Waging war with these people would not be a solution IMO.
Let's just hope for the better.
