Thanks! Flagging uses vote power just like upvoting, and it took 20%+ each to smash down almost 100 comments now :(
This isn't something I can do full time, and steemcleaners does a great job but we really need more people with SP to be willing to use it flagging abusers like this..

We will help you out! I was looking for such a community.

Anyways. If the signature of the this type of abuse is the amount of upvotes, it should be fairly easy to write a bot to identify potential abusers. Many third party steem services already count the number of upvotes, so i'll leave t to them to reuse/reorganize their code rather than reinvent the wheel.
However that said, if a hoard of bots is all that it takes to shut down a user. Then someone could use bots to mass upvote legit speakers, particularly those who speak about certain contraversial topics, just for the purpose of administratively shutting them down.

If such abuses continue. The system will likely have to be changed to a maximum of the top n upvotes, or a percentage (perhaps declining as the number of votes increase) past n.
