Zeal 2.0 uses a variety of unblocking and localization techniques including using proxies based in different geographies, diversifying our user-agent string, and scraping sites at different times of the day.
Our approach to that problem is to maintain some amount of consistency on platforms of concerns to act as a control (using the same keyword every day) while also applying the deep crawling and discovery strategies we use (reverse image searching, generic scraping, AI keyword generation and dynamic scheduling)
Applying much more intelligence to the scraping behaviors, we will be able to surface more infringements on those platforms than previously.
