You said it yourself...it's suspicious at the most and unethical at the very least. I think having different identities is ilegal in any country of the world.

@smooth has almost 100 different accounts (I got this number directly from him so there's no secret about it). I've jokingly "investigated" them here.

He transfers SP in a cycle, so he gets Steem daily by powering down from many of them. Yes these are the rules of the game, just don't expect zero controversy, questions and doubts.

This and many other issues are evident and not very good for the integrity of the platform. Don't expect companies or smart investors to start throwing big money over here any time soon.
