@bashadow explains it well below... we give out a $2.00 upvote for each $1 sbd in deposit or 2x... you don't make money off our bot... It is a service to help you pick up your own dust... so we use your sbd, turn it into a payable vote, and then your dust sticks to it.
It happens on the 5th or 6th day after the vote or comment was made.
