Fuck that.
Sorry if you have doubts how about you call me up on the phone and talk to me for five minutes? It can't take any more time than this sort of thing would waste for the both of us. How many scammers will be able to bullshit their way through a five minute phone call?
Besides for all the affiliate fraud there is what about sponsor fraud -- particularly sponsors closing up and leaving affiliates high and dry without paying out their earnings and stealing rebills? It goes both ways.
