Jesus, yeah, good point. If they're just flooding a single address like that, I'm sure Amazon would just shut them down before they could do any unique whitelisting.

I figured their user-base was fairly... "static", the same primary users generating a big chunk of the relatively small 500GH/s. If you could quickly and easily enough whitelist those users... at least you'd maintain a good chunk of service.

Obviously it'd screw over everyone NOT on that whitelist, but letting me some people mine is better than nothing.
