Don't think Yorkie was calling you a cheat personally, Winrew, he was simply saying that he posts the screenshots to avoid the possibility of anyone cheating (i.e. everyone has the same odds for the same selection, as long as it's one of the leagues he posts screenshots for, it rules out the chance of anyone making up a higher price than the actual odds and seeing if they can get away with it). I didn't think he was directly accusing you, could be wrong, but that was how I read it.
In any case, if you've always taken the prices directly from the Bet365 website, I dare say there will also have been times that you've got a shorter price than you would've had if you'd taken them from Yorkie's screenshots, probably all more or less balances itself out in the end.
