In your past E-Mail you mentioned your Tor relay nickname, I looked it up back
then, and it was a dedicated server at OVH.

Thing is, I also rent such a server, and has been running exactly into the
same problem with Google. However I do not run a Tor relay on that server.

If you take a closer look at the CAPTCHA page, at the bottom it should mention
your IP address. Check if it's maybe the IPv6 address of your server
(2001:41d0:...), in my case it always was. If yours shows IPv6 too, then this
issue is definitely not related to Tor, because in the default configuration
Tor does not use IPv6.

I suspect this is either a misconfiguration on Google's part, or indeed a
large number of Google scraper bots running in OVH's network.

For me the solution was to just abandon using the Google Search and switch to
StartPage[1], which aside from a number of privacy-related benefits[2], also
looks like Google from back in 2004 before they ruined it with all the damn
AJAX and "Web 2.0", which in my opinion is completely awesome.
