My website is being constantly hit by scrapers from EC2 machines http://d.pr/i/bLtE . I went aggressive and blocked all access from Ec2 IP’s http://bit.ly/SUOaof until I realized that quite a few reader proxies like Flipboard are based out of Ec2 and blanket blocking of these amazon machines wont help. How is the community dealing with this problem? Can you advice?Edit: I’ve seen somewhere that Stackoverflow blocks all the ec2 machines. I don’t think this is the most optimal solution considering many legit services. Also the hits come from different ip’s.
