What is www.facebook.tk and why is it unique as opposed to other www.facebook domains not owned by facebook?
Facebook.tk is unique because the Dot TK domain is synonymous with facebook due to a partnering arrangement already in place between facebook.com and Dot TK allowing facebook users to shorten their facebook account pages with a .tk name.

Due to this arrangement there is a trusted brand recognition already associated and familiar to millions of facebook users as opposed to www.facebook.(whatever) domains not owned by facebook. This is an opportunity to own a trusted, legal, and recognized www.facebook domain.

In 2010 Dot TK also entered into a similar arrangement with Twitter account users further strengthening the  familiarity and brand name recognition with millions of Twitter users.
