The bots aren't the problem. You used them yourself to bring attention to your post and spur engagement. The problem is you have some users posting multiple times a day and being disproportionately rewarded thousands of dollars for redundant content.
It's inexplicable that some of the Witnesses around here feel compelled to cap the price of SBDs at $1, but have no problem with there being no upper ceiling on the earnings potential of any given post.
The recurring rewards of sub-par content contributions is unsustainable and a fundamental flaw of the Steem blockchain that continues to remain unaddressed. Until there is a systemic fix, nothing will change.
