So you didn't consider taking collateral as the amount was almost negligible? Why bother opening a thread anyway?
The account hasn't been active since June 04, 2018. Maybe they are busy IRL and would pay back once they come online? Regardless if they pay or not they do deserve a negative feedback for being a untrustworthy lender.
I opened this thread so the possible scammer gets tagged, at least temporary.
The amount is as you said negligible, and I am totally OK with taking the loss here.
