This is why I set-up Facebook for the forum to send threads into, but I would never use it on a more personal level other than that. It's a bit of a CON really, they have all privacy permissions to go though on your account (a total minefield design to be just that) a minefield of confusion. Then when all is said and done, they can still be over-ridden like the thread starter indicates, one wrong accept click and your giving away things you might not even be aware your doing.
Has anyone noticed how they have moved the CLOSE ACCOUNT link to another location now, one that takes you hours to find and is no longer that simple to locate anymore. I closed an old account last week, it took me hours to find it, they are very crafty and shady how they go about things.
