I had a killer whale which walloped me every month for about six months. This program carried forward negatives. My aff manager kept assuring me not to worry, that the whale would “eventually give it all back and then some.” Since I had been earning over $20K a month with this particular casino I listened and hung on. Eventually that damned whale had ran my Negative balance up to $1.4 million (or so that stats would indicate). My account was ruined.
The casino finally offered to switch me to CPA and remove the whale (they also removed all the hundreds of producing players I had). I dropped them.
