I used a German proxy for less than 10 minutes to access a certain website the last night. I did not register/login to any website using that proxy, or accessed any other German website other than a German University Website. I did not even click on any Advertisement links.

And I started getting advertisement mails that originates from Germany based websites [Not related to what I accessed using the German Proxy].

Now, what I think, is that this cannot be just a random thing. I've never used a German Proxy before, neither did I ever visit any German Website except in this case.
And getting half a dozen mails from Germany-based websites right after using a German Proxy and accessing a german website cannot be just a coincidence.

So, how did those German Websites get me email id suddenly?
I think Google is behind this, silently sharing the user details to 3rd party websites.
