cause this is what happened to one of mine (dating). i am on their ppc thing where you get x amount of cents per click depending on your ratio for clicks/signups. well a bit into the pay period they changed it so that instead of having a 1:2 ratio for x payout you now need < 1:2. my ratio was about 1:2.38 so it rounded to 1:2 but now it says it is 1:3 and all monies from the entire pay period were lowered to almost 1/2 of what they were before.
