Just because I'm nosy, how many individual returns did you generate? I've returned three motherboards in a row (all from the same malfunctioning batch) that cost over $150 each, and never got a warning or whatever. So for less than $100, I cannot imagine why they'd take this action. Is it a lot of returns on inexpensive things (e.g. 20 $5 items).
