I'm thinking of using the fiverr script to create a similar site but has anyone actually used this and does it work Ok or is it buggy? What I most wanted to know was about PayPal. If there is loads of Money coming in an out of your PayPal account from your users how on earth can you track how much is actually yours? With people withdrawing at random times and various commission structures etc I can't work out how you can possibly know what cash in your PayPal account is yours and what belongs to your users. Anyone know? Also is this likely to get your PayPal account limited? I'm always paranoid about PayPal after having problems in the past, I can see their filters being triggered with hundreds of payments and transactions all of a sudden? Any help would be much appreciated.
