Party, it's the act of using a promotional product to it's maximum. They deem this as a professional approach. Their promotion is simply a marketing tool to attract new business. They don't want people using it as a strategy.
Their last condition sums it up...

You'll find any bookie that offers promotional products that punters use to the maximum, will be locked out as soon as they have a win, if not before.
The bookie doesn't individually sit down and think "I've had enough of this joker" their sophisticated software flags winners, large bettors and people that utilise promotional products above a certain limit. You are marked and chances are that info is shared amongst affiliated bookies, so you might get shut down very quickly elsewhere as well. I have long been of the opinion that these offers are the exploding briefcase for punters. Grab it and they know....you are one of the savvy punters they don't want.
It really is grubby business, and they have no right to call themselves bookmakers. They do not make books. They engineer their client base to only be fluid with casual mug punters.
