RE: Manipulating google ad traffic -> not likely, google'd detect this.
RE: Buy structure -> Yeah possibly, but then so is every other foundation expense, I paid for the coinpayments integration and got GRC in return.
RE: Affiliate program - GRC isn't a company, we don't have the ability to track who referred a user to BOINC and google have put a lot of research into preventing ad abuse - making our own affiliate system would be a nightmare.
