I don't think this is about a "protected" person possibly scamming. I think it is more about what would happen if *anyone* scams TF.
It's an interesting experiment, but the value of it is eludes me. TF won't lend to a member with red trust, so it's almost like he wants, or needs a member with a good or neutral trust score to scam him for the experiment to work. And if or when that happens, what then? Does he expect DT members to stand by and not tag the scammer?
I previously stated that it is my belief that part of the experiment was to see if someone with reputation to lose would scam him, so he doesn't necessarily need to get scammed.
I am not sure what his end goals are, if any. He might be trying to see if it is safe for him to trade here.
