Guys support natural steemit. see that how this type of bots harming the people. You can read promobot terms of service. here you can see the minimum Roi limit is -3%.
So friend here i want to say that how it playing with you. First they collect bids of all members and then add it in one round even you transferred bid early. And then you can see the roi in below:
So it terminated own terms of service and the bidders losing money. according to it's terms of service the roi limit is -3% but you can see in above image that roi is goes to -33% so the bidders losing money here.
So friends please be aware from these three bots @Booster
