@Initscri: I could open a scam accusation topic. I didn't create one coz I was embarrassed. Few days ago I created one when lost 0.08BTC and now if I was creating another one for losing 0.002BTC then others might laught at me. I mean consider the amount - it was only 15$.
My problem is when I see people are in need I just can not hold myself when I have the stuff they need. I know behind those people there could be two hidden agenda: good or bad. It feels me bad when I see good people do not get a chance for the bads.
I understand where you're coming from, and it's entirely up to you! I don't think anyone would think of you differently for losing money in loans. It's sad how common it is, and I'm sure most people who have loaned BTC in this forum have probably lost some amount at some point in time.
+ to scam accusation threads is it starts to open up information about the user, which may be evident/discoverable if they try to create a new account on BitcoinTalk. It puts that info on record, which makes loan stealing less advantageous (especially for this user, since he's used this username on more than just BitcoinTalk)
On the monetary amount, it's probably not worth it. But, in principle, I'd do it personally.
