I think your promo bot actually does nothing. I bid 1 SBD ($2.34) and your bot said that I was to receive $12.96 in up votes but I have receive none of it. Furthermore, your bot says that the Last Vote 4:06:23 but the reality it accepts bids about every 30 minutes.
So it appears to me you have an open scam running here and that is just NOT being an honest and fair member of the STEEMIT community.
