I am not a DoS/spam expert but first things come to mind are : - Google account credibility (I have a very old Google account and this should provide me some trust from Google's perspective) - Malicious word analysis in search queries - Browser/device information to determine authenticity of the search (if I am at home or connecting over a Tor network) - Gradually increase the response time for the queries On top of those, Google is a machine learning company and I am sure this process should be automated by now without requiring filling of any active captchas.

Honestly if I could pay Google to revert whatever they did to their engine $5 - $20 a month for better searching and absolutely no bubble or tracking WHATSOEVER I would. I would pay roughly the same to any competitor.

I just want to go back in time to where Google found the code I was looking for. Seems to be after they started filtering results strictly and trying to maintain a bubble around specific users.

I pay for a JetBrains annual subscription to all their IDEs I would gladly pay for a search engine that only filters out whats illegal to a reasonable extent (piracy filters shouldnt be extremely aggresive to where it cripples everything).
