I have heard of some Facebook users who will create a profile based on a ficticious character and then add friends who show interest in a specific niche or product type. For instance, a person might create a girl gamer Facebook profile and then add other gamers interested in playing Xbox games. This is only an example and you might think of others. Anyone added to the friends list would be a gamer and not a real friend. And, the person with the fake profile could then post links to their own gaming related site/blog/forum and ask friends on the friend list to like their favorite Facebook page. Have you used this idea?
