Thank you for pointing this thing out to the community. Had no idea there was such a thing.
With both Dan and Ned, Jerry, Steemcleaners, on the list, and the 40 SP review fee, it's very clear the list is extortion of some kind. Steem, Inc., the owners of the website needs to get involved. (Otherwise they expose themselves to liability.) The other people on the list, some of whom are, in fact, imo, really spammers, are apparently there for the mere "appearance" of it really being a valid list. Such things have been done before . . .
No problem. Failed extortion, if that's what the plan was, as no-one has sent any STEEM. I'm sure we've not heard the last of this list though, cheers!
