Its basically like pay-per-click programs , unless your cheating or a moron you realise " hmm if they can afford to pay me .5 cents to post their sig , then they must be making more off me than im getting paid " so why wouldnt i just have my own sig that pays me real profits ..
Once you stop posting you make no more money
But on ref programs the money just keeps adding up and up and up.
I signed up a few big players back in the day and they made me craploads of money while i was on vacation. All the sig whores gotta keep posting to keep getting money lol.
