Agreed. And any response will be a simple 'we are still discussing it with them' / 'we cannot enforce the law' type thing which is about as far as this is going to get surely.
I'm not suggesting GPWA should enforce the law, but obviously the sponsorship is a key factor as I presume it's in the thousands of pounds. I would have hoped this thread was enough evidence to boot them instantly to be honest.
Another reason that regardless of a brand having 'platinum sponsorship' or whatever, I'd rather hear first hand experience from affiliates rather than pay attention to that 'paid for' nonsense or be suckered in by "30% lifetime revenue" rubbish.
