perhaps I might have skipped giving it.
I have skipped too and lately sent only 50$ but while the user joined the campaign and asked for another loan (500$) I thought 550$ risk is okay as the user is in a campaign and the activity is good enough (based on the merit).
$180 and leave the forum is stupid.
I noticed rising number of loan default scams, this has become a very risky thing to do in bitcointalk forum.
The user defaulted a total 700$ and including interest, the total amount is 940$.
I hope that he will respond
He will never respond.
