Potentially yes. I'm not sure that vote buyers would top everyone's list for what needs flagging first. Alternate account voting farms and circle-jerks could be up there too?

I wonder how the amount of Steem bought for bid-bots compares against Steemit Inc's constant selling. Improve the place, bring in ad revenue, reduce/stop the selling and the price could (with the help of BTC) rise even with a reducing in vote selling?
