> Simply observe the event in which a user does a query q in Brave and then, within one hour, does the same query on a different search engine. What we do is to move the script that detects bad-queries to the browser, run it against the queries that the user does in real-time and then, when all conditions are met, send the following data back to our servers.
Wait. Brave browser sends back to Brave Search engine about your browsing? Other search engines usage, but also crawl pages on your computer to help build their search index?
