It doesn't matter if it doesn't make you a profit. What matters is the drain on the reward pool for everyone else by you purchasing votes. It goes against all that the EIP stands for. If it is promotion then you shouldn't profit from it so there shouldn't be an issue?

Also you used BDVOTER

I quote - UPVOTE & Post Age [ 5 minutes to 3 days ] ! UPVOTE ROI ~ 200%

ROI implies return on investment. So no profit, you say??
