Just because some info was blanked before it was reproduced on the internet doesn’t mean that the certificate itself becomes invalid. I’ve seen some weak Birther arguments around here, but that one takes the blue ribbon.
Since this electronic version is the only certificate offered as "proof" then it's no proof at all since the document clearly says "Any Alterations Invalidate This Certificate".
It's an invalid certificate because there's an alteration made to it. Sorry.
