IMO, the purpose of this is to see if people are willing to scam a scammer and if anyone is willing to do anything about it (leave negative trust).
Isn't the answer to that question already obvious? "It depends".
If 3-People scam then they will all receive different reactions.
If (almost) anyone else were running this experiment I would happily take the "loan" to aide in your research with the caveat of neutral feedback or no feedback, but given your current standing (inb4 hypocrite) I feel like participating in this might assist you in scamming members in the future.
TF doesn't say anything about a "lending service"...

Sure about that?
I'm offering a 0.02 BTC loan
Isn't offering a loan, with qualifying-criteria to multiple people exactly fitting the definition of a lending service?
