The OP explains the reasoning; in 2014 Satoshi's email was hacked (or recycled) and therefore the associated P2P account was also accessed. Note how this happened in 2014, including a post on his P2P account, so it seems the same thing has merely repeated itself. Minus any emails, possibly. A lot less interesting in 2018 than in 2014

Simple analysis: Unless it's PGP signed from one of his early mined blocks, it's not Satoshi.
