Hi @screened - in general I agree with you that bids from blacklisted users should be refunded, and the @postpromoter which I run does that, however I know most of the other bot owners do not agree with me and do not do that.

I am working on adding a new feature to the bot tracker website which will allow the bid-based voting bots to publish their rules or terms of service where they can make all of this information regarding how they handle blacklists available to everyone that uses their service.

Hopefully that will help with these issues in the future.
