Hmm. You leave out an important part of the timeline: Todd’s October 10 post occurred 90 minutes after Satoshi’s post — the one that the HBO doc claims Todd was trying to amplify as Satoshi, just that he accidentally logged in as Todd instead. I don’t want this doc’s claim to be true, but it seems quite a coincidence that Todd, having only logged on once before two days ago, happened to log in and reply to Satoshi just 90 minutes after Satoshi posted.
