HBO believes that Peter Todd is Satoshi Nakamoto in several major cases: misusing his own account to reply to Satoshi Nakamoto's posts, etc.

According to Foresight News, @tier10k summarized that HBO's documentary on Bitcoin tried to show that Peter Todd was the founder of Bitcoin, Satoshi Nakamoto (but Peter Todd himself denied it). Some cases include: In 2010, Todd (using a new account) replied to Satoshi Nakamoto's post on the Bitcointalk forum; HBO claimed that he mistakenly used his account to complete Satoshi Nakamoto's post. Both accounts stopped activity a few days later. Todd later implemented the "Replace by Fee" (RBF) concept discussed in the post.

Additionally, a document provider claims that Todd used the pseudonym "John Dillon" to promote RBF. Both use British/Canadian spellings. In addition, Satoshi's posting schedule matches the schedule of a student claimed by the document provider, with more posts on weekends. Todd has discussed "sacrificing" Bitcoin; this may refer to destroying Satoshi's Bitcoin.
