If an evil person wants to get airside, they will just buy a ticket. I don't see too many people using the refund game to get airside, plus I would think airlines might catch onto an individual who constantly buys a ticket, checks in, then cancels.
Businesses do this all the time for their employees who may or may not have to go to a meeting and the decision isn't made until the very last minute.
There is no way to prove someone was just buying a full-refundable ticket for airside access unless the person confesses. Were I being grilled about refunding tickets, I'd tell the person questioning me 1)there's a reason fully-refundable tickets are sold (and are expensive) and 2)to go do something biologically obscene to themselves as it's none of their business why or how I choose to do my traveling.
