I am scraping ezinearticles with a botload of proxies and my own bots. Still, I am not satisfied since they ban really fast. I need f***ing more articles. Did anybody research on which base they ban? Time of subsequent requests? Some header info missing? I just checked the WP bad behaviour plugin, this reveals a lot of methods to ban unwelcome guests. Many combinations of headers and user-agents are revealed as being bot. Any recommendations?
