I'm logged into Facebook and viewing my wall. I notice that John Doe likes Some Fake Page
I wonder.. what's Some Fake Page?? So I click on the link and it takes me to an external site.. But wait! That's not all!
I now officially like Some Fake Page! Did I actually click on the Like button for Some Fake Page? Nope.
The bottom line?
1. Facebook doesn't tell you if you're about to navigate away from facebook.com (to an external website).
2. Some like links might cause you to like those pages without your consent.
How did I get rid of the newly liked link?
1. Click on 'Edit My Profile'
2. Click on 'Likes and Interests'
3. Show Other Pages (if applicable)
4. Remove the Page
