I didn't know Adguard has an "allow acceptable ads" feature. Looking at a YouTube video, I do see a "Do not block useful ads" option which appears checked by default. Along with a "Find out which ads we consider useful" link which the reviewer didn't go into. There was also a "Take part in the development of a browsing security module... you agree to submit anonymous security related information to the Adguard server" option I saw. Has anyone here taken a critical look at those two features to assess the privacy/security impact? What are users of those features exposed to?
