Once an aff manager manually added $1 to my account to reach the minimum payment requirement. Then removed it next month. On other occasion, another manager added click counts manually when I complained that the tag wasn’t working when put the banner on my site. I know he added it manually because the number of clicks were much greater than I made on the banner and it was before the page was published and after that the tag still not worked. Still with another company, all my active players dissappeared for two weeks, as soon as I complained, the players were returned. I’m positive that the stats can be altered any ways.
