I am talking about the petition at:

http://www.fsf.org/campaigns/secure-boot-vs-restricted-boot/statement

Filled in my name, surname and my gmail address and pushed sign. The next page tells that I will receive an email with a link to confirm the signature. I waited for the email, after some time I got suspicious and checked in the spam folder - nothing there. Thought might be a bug in the systems, tried it again - 3 times. Does not work.

Luckily I have another non-gmail account - tried with it and it worked immediately.

So what's going on? Is FSF blacklisted somewhere, or maybe FSF does not want to send to Google? Did you have the same experience?
