Fair…I can’t know how much tracking is blocked, if any – Legacy 1Blocker Review

I cannot help but deduce that there is a failure in 1Blocker’s blocking of trackers. NO improvement over when 1Blocker was NOT installed. My default search on both iPhone and iPad is duckduckgo. I have 1Blocker “Legacy” set up to block tracking. My email is via Gmail. I regularly purge ALL of Trash, Spam, Inbox, and Sent. I often clear browser data. Safari settings include “Ask websites not to track me” and “Warn me of fraudulent websites” (which I always obey). So there. Yet still, when I search on a topic in duckduckgo, magically within a few hours, I begin seeing emails (most often Spam thanks to Gmail) on the topic of my search. Of course, I never open them, just glance at the title. So, praytell, what good is 1Blocker for blocking tracking?
