The self voting seems to be a continuous issue... I honestly don't know what amount is right or wrong . What I do know though is that people that put hundreds of thousand into Steemit probably will treat their investment very differently than a lot of people that earned most of their Steem on the platform.
We have to think about the opportunity cost as well. Also it seems that people that have more SP get more scrutinized.
By now you would have to put millions into the platform to 'rig' it for self-voting. Otherwise it won't be profitable for the 'self-voters' because they have to put their assets into steem for a long time. Which is quit risky.
Totally agree with that. I guess there is a conflict of interests to a certain degree between the people who have invested in the platform financially and the people who invest a lot more time in creating content and curating content. The balance of power here is always going to be an issue.
