These days I have published a Python 3 module intense used at TheWebMiner. The module it’s called PyTor and it’s available here: https://github.com/adibalcan/PyTor. It helps us to avoid CAPTCHA or other mechanisms for blocking the robots that crawl fast, websites. With this module you can detect when a website ban your IP address and you can easily change it (actually this happens automatically). Now this module it’s public and you can use it in your application.

I hope that it’s useful for you.
