I wrote about a similar situation on a blog a while back. This is the work of a small group of people who have decided they are the policemen of Steem and use their power to suppress what they consider scams, and of course, while they are at it, they make a bunch of money. Here's my blog: https://steemit.com/steemit/@infinite-monkey/how-steemit-disincentives-dissent-and-drives-people-away-a-minnow-s-perspective

But remember, don't confuse steemcleaners with Steem, one is an account, the other is the website/currency. Furthermore, your blog can't be erased from the blockchain, although it has been flagged so it is not as visible to other people. There are a lot of benefits to steem, unfortunately, there are people like these guys we have to live with.
