No, Brave Search won't copy search results that users do not click on. You own your queries and clicks. Only users who opt into anonymous logging to help Brave Search send unlinkable records up, and those records are not scraped from unclicked links in SERPs.

I was referring to this bit in the top level comment:

> In my understanding what Cliqz did, at least in the beginning, was to buy clickstream data and then build an index on top of that

I don't know if that's what cliqz actually did, but if they did do that it sounds very similar to what bing did.

From https://www.siliconfilter.com/hiybbprqag-google-claims-bing-... it seems Google engineers laid a trap by using IE with Bing Toolbar and Bing Search Suggestions enabled. Not clear what was gathering the data, but this article doesn't say whether the Google engineers clicked on the bogus-keyword's result link. If they did, then clickstream as you say. If they didn't, something in the IE+Bing mix scraped links from whole Google results pages.
