If you had a cpa offer or some sort of offer that was rather simple and paid good for a free trial would it be possible to simply post an ad on dp or somewhere saying you will pay someone 10 bucks to sign up on a site for you. Would this not work? and you could set up a landing page or something for them to go and click through (so it would seem legit to the company)...and then you could offer someone 40 bucks or so every so often if they try the trial and agree to let the offer turn into a membership for a month...to keep suspicion down. Would this not work?
