The 10 cents to the dollar allows you to absorb some fraud. You also check the applicants records, and for those cases where there is too much uncertainty offer payment only after a successful lawsuit (you my want to pay out 25 cents to the dollar in these cases to reflect the reduced risk).

I'm not sure if you understand what the fraud ratio is. Especially in the beginning, you should expect 99 out of 100 users to be fraudulent.

Basically, in order to make this idea successful, you have to solve the fraud problem a lot better than Google does... which seems unlikely.

There's a famous music sharing group where you can only become a member if someone vouches for you. If someone snitches, then they are thrown out of the group along with the person who vouched for them. (Or something like that.)

This sort of system seems like the right idea for preventing fraudulent sellers.

That seems absurdly easy to game... but even if it worked, wouldn't Google or PayPal be doing it?

i like this system of enterance .please vouche away. harden rock.
