Some advice; stop using minnow booster.
That goes for any other pay-for-vote services. Steemit used to work because the whales had incentive to vote to earn curation rewards. As long as people such as yourself continue to offer these whales a chance to sell their votes while they can still earn curation rewards, there won't be much of a reason for them to vote naturally.
If whales would vote for real content rather rather than some "I'm new to Steemit" selfie for $200, then sure. Otherwise, I waste all my time on Steemit for nothing. At least MinnowBooster allows me to magnify my SBD and add some Steem to my wallet. I'm honestly getting tired of producing excellent content to be ignored. I have a select few committed followers which is great, but most upvotes are very minimal. If this problem gets solved somehow, then sure, I'll absolutely stop using MinnowBooster.. why would I need it then? Unfortunately, Steemit is currently a neo-feudal estate that doesn't build its middle class. This can only end in tears for everyone if the incentives don't change.
