You inspired me to look at the front page to see if there were any posts with lots of votes but low value. After scrolling and scrolling and scrolling, I found two:

The following post has 19 votes and a value of $3.14 as at the time of posting:
https://steemit.com/bitcoin/@canhazlulz/andreas-antonopouloss-latest-talk-on-blockchain-deloitte-fintech-talks-event-in-milan

and the following post has 37 votes and a value of $3.84 as at the time of posting:
https://steemit.com/steem-marketing/@nanzo-scoop/jokes-aside-part-2--nailing-down-the-dollar-amount-steemit-ux

So you would need a lot of people voting just 'cause they like your stuff, plus ignoring the "no more than 20 votes" thing that appears to have gained currency (which prevents people voting as often as they would really like).
