So I was skeptical of 
I've now placed 5 or so successful randowhale orders and each time I got more back than I paid in. (at least as far as I can tell)...
But even if it doesn't work for making more money off of your posts, it could at least increase your reputation.
Currently my reputation is at 42 and earlier today it was 36!
However...don't make the same mistakes I did.
- Votes on posts that have already cashed out don't make you any more money!
- Randowhale won't vote if the post is going to cash out in the next 12 hours
- Note the spelling: randowhale

EDIT: Just a rough calculation...randowhale upvoted this post which was 4.6% = $5.60.
So the minimum you could get is 1% = $1.21 and on average you'd expect 2.5% = $3.04
