At home today we hit Google from so many different VMs and machines running from so many different OSes that we triggered the captcha to verify that we’re human.
Well, I suspect that I am not given the evidence — but still this was not bot traffic.
I just use a lot of VMs whose user agent strings will differ, and was doing Google searches from most of them.
Google is not expecting a dozen different machines all with different UAs to hit it from a residential address in a short time, I guess….
