Hi folks, I'm developing a free SEO tool that checks PR for thousands of domains with PHP Curl. The problem is that after a while I get banned. The proxies I'm ussing (http google enabled ones) work great with Scrapebox: I check over 90000 domains with over 50 proxies in 3 hours. But I don't know how Scrapebox server hide this public proxies. Any experts in this area of knowledge?
