As others have said, Google's abuse systems are smart enough to understand NAT and proxies, and won't block on request volume alone. When we automatically apply a block, we'll generally offer a captcha to give innocent users a workaround and limit the annoyance until the abuse stops and the block can expire
This failed at our site. Our entire IPv4 and IPv6 addresse blocks received captcha after captcha after captcha, forever and ever.
There was a link on the page to get more information, but all that got was another captcha.
Normally I am 100% behind Google in everything, but sadly, this has now fallen to 99.8%.
I've triggered Google's CAPTCHA multiple times at home, just from rapidly adding and removing search terms, in a couple of different tabs, after driving down a hundred results or so. It's been a few months, but this used to happen to me pretty regularly if I had drive deep to find something. Royce
