Not always profitable? You had over 200% ROI.
While it is true, there is no guarantee it will be profitable, it is typically. It is not a cash machine, it is a promotion tool and we also give a lot of upvotes prior to our vote coming around, I know one user who has a $7 upvote that you can get by using our service.
But it is fair, we do not minipulate the bids, or add our own bids which is more common than you would think.
