this is the message i get from google when i use my proxy
"Our systems have detected unusual traffic from your computer network.
This page checks to see if it's really you sending the requests, and not a robot."
This is a common security measure. A single user can only generate so much traffic doing normal things. So, companies like google take an estimate of the average user's workload, multiply it by a large number (like 100 or so), and say there's no likely way that a user will generate more traffic than that in x seconds. If you do generate more, then it looks like you're spam, so it makes you prove you're human. When using a proxy, you're being masked as a different endpoint. That endpoint is often shared with many other proxy users, and so the traffic load is often much larger than that threshold of "normal" volume, so Google realizes something is wrong, and makes you prove you're human.
If it's Tor you're using, thats a different story. Google watches for tor endpoints, and forces extra security restrictions on those users, or requires steps that identify you (like clicking on the many boxes showing images. identification is done by mapping your tor patterns of inputs to your nonencrypted patterns).
