I am a total newbie at this. I decide to do some scraping and have heard to use free public google passed proxies for it and to avoid using private proxies. I heard to only use private proxies for commenting. The problem is, I can't seem to find one... if there is. It's giving a lot of error 404 on scrapebox. How do you guys go about doing this? How fast do private proxies get banned in scrapebox?
