I have started to wonder whether it is possible to 'game' the system for maximum rewards. If you can see when someone is going to buy a big upvote, then couldn't you jsut upvote the content just before the bot does and you would have 'curated' some highly 'valuable' post?
Yes, there are some people doing this and it seems to be highly competitive over who has the best algorithm in their beat-the-autovoter autovoter.
A different way to maximize is to focus on voting dTube posts, as dTube uses beneficiary rewards to operate a second curation system on top of the normal one that brings total curation rewards to about 40% of the post rewards.
On a different topic I'd like to draw your attention to https://steemit.com/@tcpolymath/apply-here-for-dolphin-support-0-300-sp-accounts which is a support project I run. I'd be interested in seeing an application from you.
