Got an email this a.m. supposedly from Facebook Security asking me if I was having trouble logging in and, if so, to click on the indicated place and they would log me in. If I was not having trouble, I should click on the other place to let them know that.
Well, I have not used Facebook for years and, in fact, closed the account down or at least "put it to sleep". So I am guessing this should just be ignored with no click on anything. The address at the end kind of gives it away. "1 Hacker Way, Menlo Park, California"
