They need to find a way of ensuring that the only accounts that can join the queue to start with actually have the required credits
Or even just stop them basketing if they don't qualify if they can't block you from queueing (which I'm sure they could).
It's possible as with the priority rights sale and the +1 from 19/20 you couldn't basket unless you qualified. Might be new, I've never actually noticed, but they can do it at least.
Loads are just queueing and basketing and then selling the basket to someone's account.
Also needs to be done with local sales, can't be hard to see ID and save this to the account as a local member.
