Origins: This warning about a "hacker door" is yet another bit of Facebook scarelore which began circulating in May 2010.
An odd glitch that has cropped up in Facebook causes users to show up in their own friends ("All Connections") lists as friends of themselves, and such entries will typically reappear even after they have been deleted. Strange behavior, perhaps, but it has nothing to do with "opening a door" that allows hackers into one's Facebook account — having your account name show up as your own friend has no deleterious effects in Facebook.
