1. I don't think BPB actually asks for positive trust. He has given me gift cards a few times and never asked me for any kind of rating or a vouch.
2. I can think of a few people who won't accept escrow who are pretty well trusted, and I wouldn't consider them to be scammers. I don't think escrow really matters anyway because a) he asks for people to donate money to charity for payment for his gift cards, and b) gift cards purchased with stolen credit cards can take months to be discovered that they were purchased with a stolen credit card.
3. People on default trust tend to be more active in market place sections and they tend to not be shill accounts. To see why people might not want to give things away to people not on default trust see
this thread, you will see that some people tend to claim giveaways multiple times via shill accounts, and that is simply not possible with default trust accounts because there are so fewer of them.
4. I don't know how to respond to this. I think it is speculation though.
5. I have had conversations with him via PM a couple of times, and I am sure that others have done the same.
6. He usually gives pretty steep discounts, and I would somewhat doubt that he would be able to sell so many gift cards at that discount in order to make up for all the money he has given away. Also as mentioned above he usually asks that people donate to charity in exchange for his gift cards.
Sure, proceed with caution when dealing with anyone on here, however I don't think you are making good points against BPB
