I have never seen a captcha in google search and my search patterns are pretty similar. I also usually hop between vpns to be able to access libgen, scihub, etc and still google never seems to think I’m a bot. I am using chrome on mac and I’m logged in chrome with my google account. I wonder if the last part makes any difference.
