In browsing some other freebie pages I came across a site giving away thousands of beta keys for GR:Online
the site can be found Here
when i got the key a week ago there were over 30000 left, i cant find out how many they have left but i know they are still giving the away.
you have to register and keep clicking the apply for beta key until they give you one, if you dont get one right away, keep trying, the clock resets after 30 seconds so you can keep trying to get one.
once you get the key just log into the gr:o site and activate your key.
if you have any issues by all means ask for help but dont expect someone to give you a key for nothing.
PS - Please note that this site is NOT an official support forum. If you are unable to enter your beta key after applying for one in the first place then please contact the ubisoft support team and raise a ticket. I have posted a load of links further down the page. I cant do more than that.
