Yup. I envision it like some vulture capital firm in the business world buying up stake in a company, selling off it's assets and bleeding it dry at a tidy profit and moving on.
It really got under my skin when I saw a user who literally only up votes themselves, 100%, make a post touting how they're stopping their power down because they're so committed to the platform and asking for others to help them reach their Steem Power goals. That just seemed a bit too audacious to me. And they're getting legitimate sincere votes from other users who have no chance of it being reciprocated. Not everyone goes into a blockchain explorer or keeps an eye on stats, most would not have any way of noticing this kind of behavior.
I'd like to see some kind of visualization, badge, meter, have it factor into rep score, whatever. If someone comes on the platform and never upvotes another living soul, I don't think they should be able to build up to a 70 rep. I'm sure if people saw this community building metric at a glance, it would influence their voting behavior.
I was thinking along similar lines. If all comments and posts made it clear if the author voted them up, that would be interesting also. The reputation score might some day include all of this behavior, good and bad. That would be cool.
