Imagine the user toke a 100usd loan and he did't not payback, here by recovering the 50usd from campaign the can recover 50 percent of the money. Recovering the 50 percent is definitely better than nothing.
Are you suggesting that the campaign manager should send weekly payment to the lender in case a campaign participant defaults on a loan! Well, imo, this can/should not happen without the participant consent. Besides, he can simply stop posting if he realises he is not going to be paid.Also, CM should not intervene in whatever deals their participants make and should not be held accountable if things go wrong.
Just my 2 sats
