Stop blaming CCbill for "turning on or off the scrub". Those theories are just plain wrong. If you have a high chargeback rate then that is just as much a problem for them. It isn't like they are just going to try to push through fraud for webmasters and punish non fraud sales by "overscrubbing" just so they can maintain averages.
They would have been out of business long ago along with companies like DMR if they did things that way.
So the "high scrub today theory"? THAT IS JUST WRONG.
DO I NEED TO SAY IT AGAIN?
WRONG WRONG WRONG WRONG WRONG.
If you want to understand why you see those fluctuations then read this wiki describing the "
Poisson Distribution"
What you are experiencing are normal fluctuations. CCbill is completely honest about there NOT BEING a problem.
Sorry I got so upset. This sort of stuff just drives me nuts. Besides, if you think that is what is happening then you should be getting your own merch account and start working with a company like Netbilling.
