Thanks, Jades. It wasn't nearly as convoluted as I thought it would be. You would think this wouldn't be that confusing for FB players...
It does not work on the new players for ID. If someone opens a new alt account you can not use their profile numbers, as Mi7ch had stated earlier they are not using Facebook Ids for game Ids. Mi7ch said quote, ". If you made a game account after a certain date, then you are given a different ID on the game than your Facebook ID." Which is the post I replied to.
Send me a link in private, I'll show you it works, you need to use the 2nd link for new accounts https://www.facebook.com/ only time will not work is if they used KANOPLAY to create the account and have no attached FB to it.
