>To avoid this, support personnel for scareware firms occasionally give refunds – but only up until the point their rate of chargebacks has dropped again<
Well surely a recurring pattern of refunds as the chargebacks approach red overload makes it obvious something is amiss. After all, all financiers are math heads and the big thing about numbers is seeing patterns in the chaos. But of course, the banks make money out of every conceivable transaction (£20 for a letter), so of course they're going to ignore a successful company, even if their job is fleecing people... Sorry, confused bankers with 'scareware scumbags' - fnord.
