And that's pretty much the point. It's the article which is claiming "emails don't appear fake" and "it looks real".
Unless its proven that the mails are real, FB shouldn't be harassed over it. If they don't have the forensic to prove it real or otherwise, shouldn't FB be getting the benefit of doubt since the guy is a convicted felon, remain silent for years, suspiciously came up with new mails months after initial lawsuit, seems excited about FB(the site he is talking about) and then goes dormant for 7 years...
