Vod's feedback in your case was a little bit harsh, given that you tried putting up collateral--I don't know anything about cargocoin tokens, but apparently the issue is that they're not traded on exchanges yet and therefore if you defaulted on your loan, the lender would be stuck, hoping that eventually he'd be able to sell them.  Does that about sum it up?

Did you get the loan you were asking for? m0gliE looked interested in doing it for you, but there's no followup in that thread.  I can't speak for Vod, but there might be an outside chance that if someone loans you that 0.1BTC and you pay it back on time and to the lender's satisfaction, Vod might reconsider the neg.  But calling him names and spamming his trust page with retaliatory negs, calling him a scammer won't work in your favor.  

People get tagged here for offering worthless collateral, because if the lender accepts it, they can very easily get scammed since the borrower (especially if it's a new account) has nothing to lose by defaulting on the loan.  In your case, Vod judged it as that kind of situation.  I said the feedback was harsh, but as I said I'm pretty ignorant about cargocoin tokens and whether they can eventually be sold or not.  If there's no chance, then the feedback is certainly appropriate.
