I have started using this site several weeks ago and I am really interested in the concept of peer to peer lending, however I feel there is more that can be done to restrict or prevent scammers on the site.  I have several loans which looked good initially, but when funded, they opened up a number of additional loans and got them funded and never make payments on any of them.

I know this has been mentioned before, but why are users not restricted to 1 or max 2 concurrent loans on the site? 

Another solution would be to decrease the credit rating every time a loan is taken out and increases it when paid back.  I agree the subsequent loans should not be funded and anyone doing their due diligence doesn't do so, but when you initially invest, you have no way of knowing if someone will take out 10 extra loan as soon as the first one is funded.
