If PP is considering fee increases it is no doubt thanks to the many claims by people who keep getting scammed.  Refunds for INR have to come from somewhere.  But maybe PP needs to have more stringent requirements for people to open sellers' accounts.  Or maybe their should be $ limit on each payment to a new seller. 

The problem for PP if the do increase the fees would be that more large sellers would go for the CC facility, and smaller sellers would change to Paymate.  It would be suicidal.
