If they are taking AA against customers because of this, I say screw them. They had an "extremely difficult" year because they got caught breaking the law. Consumers were screwed during the process and I don't detect even the slightest tone of apology.
From my perspective, I've got my own AA designs for Barclays regardless of merits of their prior actions. Namely, 4 of their cards are set for closure, once beyond the clawback period. Just waiting for the Arrival to pass the 6 month clawback period.
