Hi, I am using a search engine scraper to get some urls to perform some analysis. The scraper works is a multi threaded application that retrieves many pages at the same time. It supports proxies. I downloaded and tested a huge list of proxies about 10000. So I started scraping data from Google when I found out that my real IP got banned. It never happened before. Is there a chance that some of those proxies are not really anonymous and are sending my real IP address to Google?
