Mark, a million dollar annual turnover equates to about $2,500 turnover each day, how many of their clients can come close to matching that? And anyone with such a high turnover would strongly be expected to be winning which means they are adding to Betfair's coffers. It's puzzling that they would threaten anyone whose annual turnover is above a certain amount.

They must have a good reason/s, otherwise you'd expect they wouldn't do it.
