Where is the .01BTC that you say that you send,because i don't see any transaction...
BTW...75% interest??? OMG!!!
He asked for 0.16 BTC in private - I sent in 2 transactions of 0.08 as he requested.
Yeah for sure he did, on the lending section signed messages, repayment addresses and such should be public.
Also if you really did lend him that amount, well then your money is gone, sorry to tell you that.
I don't see anyone coming back for account with negative trust, because it cannot join with most of campaigns so i would not say your lending service started on the best kind of light.
