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.
If we dont fight this then it becomes the platform, there is no path for steem to grow if its controlled be people that don't want anyone else to join
I agree, and that's why I wrote my post and upvoted yours. We need to be careful in our criticisms though. So for example, calling it "censorship", in my opinion, is too strong, and you're likely to be dismissed out of hand for it. Similarly, it's not that they "don't want anyone else to join", but rather, they feel they are doing a service for new people by pointing out scams. They are wrong, and misguided, but the intent is neither censorship, nor exclusivity.
My guess would be that someone reported it as spam to steemcleaners and it might have seemed to be spam to them upon investigation of the account because there are a lot of similar posts on the blog. I don't think it's censorship as much as bad communication, and it probably could be resolved by discussing it in the @steemcleaners chat on discord.
