Make sure you calculate the proper risk /reward ratios of each loan taker, you dont want to end up losing money to defaulters.
You have to take into consideration their rank, their activity, their posts, their previous actions, if they took loan before, if they defaulted before ,...etc
All these factors need to be considered before some1 becomes eligible for a loan, after all its a for-profit business.
Good luck friend!

IMO the only thing you have to consider when giving somebody loan is their collateral and nothing else. it doesn't matter if they have good or bad reputation when you know that your money is safe.
you simply get the collateral (money's worth) if they decided not to pay you back.
