Google seem to be intent on destroying their $78 billion dollar market capitalisation by blocking innocent users or customers from their search engine. Have you noticed this stupid Google captcha page recently ? Captchas, which require you to visually decode some distorted images of a password and type them into a form before proceeding, are a huge annoyance to partially sighted people and they do not address the fundamental problems of spam or malware etc.
"A computer virus or spyware application is sending us automated requests, and it appears that your computer or network has been infected."
No our "computer or network" is not infected, and we resent this "guilt by association".
The way that Google has implemented this captcha block is also extremely annoying, given that on several occaisions, having typed the password in correctly, another captcha screen is presented, and then yet another one !
Google seem to be blacklisting by the IP address of our ISP's proxy server, and doing so inconsistently and erratically. Possibly they are confused by the load balancing either at our ISP or on their own systems.
If we re-configure a web browser not to use the proxy server, then our PC's IP Address does not trigger this stupid captcha block.
This is not an anonymous proxy server so it does forward our IP address in the HTTP_VIA or HTTP_X_FORWARDED_FOR headers, which, one would have thought Google would be checking against their blacklist, but apparently not.
