Ran out of emails to leak? If they were legit (and I'm still on the fence on that), everything was from back in December/January right? Has he/she leaked anything more recent?
They were legit. The DKIM checked out, and pointed directly back to btc.com and geniusesatwork.com. DKIM uses RSA-Sha256, which is pretty much impossible to fake, and I've received emails directly from Josh Garza using the same domain and selector (which refers to a specific private / public key pair).
Yes, they were from November - January, and the November ones werent DKIM signed...but that is consistent as well. Emails I have from GAW in November or earlier did not include a DKIM signature, but December and on do.
The dates are not important. The content is what matters. Some of those emails were absolutely atrocious.
