The Join Facebook date for that page was April 13, 2013
Now I don't do Face Book, but I read that as the person joined on that date. My wife tells me that that is indeed the date the post was posted and not the date the person joined facebook.
So that is suspicious.
No, that’s not the date that the “person” joined, but that’s the date that the “Page” was created. And once a page is created, the name can be changed later in the future. So ... you just create a page, sit around and wait for some big “news event” - change the name to that news event - and “get a lot of likes” ... :-)
