Related story: Way back in the day, PayPal was just getting started, and decided eBay transactions would be their perfect customer. The only problem is that eBay didn't allow scraping. So they built an entire proxy infrastructure to go around eBay's rules and scrape them.
It worked. It worked so well, eBay bought PayPal.
The side effect of this is that I got control of the PayPal proxy infrastructure since I was on the security team for both eBay and PayPal after the acquisition.
We used that proxy farm to scrape the rest of the web looking for fake eBay sites (because they would block traffic from eBay's IPs) and we had the guys who built it help us build proxy defense for eBay and PayPal.
So this could work in your favor, if you manage to constantly scrape a large target who might want to buy you. :)
