[Forums] Can't post without google script

To reproduce;

block access to www.google.com, for instance by altering your /etc/hosts and setting that hostname to 127.0.0.1

Then go to any forum post and try to preview or post a new comment.

I expected the post to get posted, instead nothing happens.

The most likely cause is a javascript requirement from googles servers.
There seems to be a very strong dependency on google, which is unhealthy. A user can't browse or comment without google being able to track his behavior.
