it is a scam
Really? cos I was ready to send that address 100 BTC, wow. Close call

Hey scammer, do you remember your overdue loan? When are you going to pay them back?

It's still showing as Overdue. Post the transaction ID. I find it odd you never contacted me to remove your negative feedback had you repaid it.
