This is really interesting. I know of one whale that constantly upvotes himself but there are a few more and none of them vote for anyone else.

It will interesting if communities develop on steemit. There were initiatives started recently post which i knew of telegram groups that were efforts to build communities on steemit but don't think it worked.

I also think comments may show the same thing. Lots of red fish trying to get upvotes from whales by commenting, and upvoting them for curation rewards
