Gregory Maxwell denies Reddit sock-puppet allegations

Bitcoin Core developer Gregory Maxwell denied using Reddit sock-puppet accounts after users highlighted identical deleted posts from nullc and Contrarian__. The accusations spread on Reddit and Twitter over at least two days in late April 2019.

He rejected the claims, calling them “nonsense” and describing them as “part of a long‑standing campaign of harassment with a goal of discrediting Bitcoin’s steadfast defenders in order to scam people into purchasing fake Bitcoin assets — same as the first hundred times they have been brought and a dozen other similar instances.”

The latest dispute centered on a thread where nullc and Contrarian__ each posted the same line, “LOL. Craig can’t code,” before both comments were removed minutes apart. The matching wording and timing prompted users to contend the accounts were operated by one person. Some pointed to similarities in writing style.

Adam Back, CEO of Blockstream and a longtime collaborator of Maxwell, pushed back in a Twitter thread. He wrote that the overlap “looks like coincidence” and argued that statements by Contrarian__ ran counter to Maxwell’s public views. He added that midmagic is “definitively not Greg.”

Some posters went further, asserting Maxwell staged exchanges between accounts and citing past online disputes, including edit conflicts on Wikipedia. Those claims were not backed by independent verification. Maxwell rejected the broader allegations as harassment.

Sock-puppet accounts are extra profiles run by the same person to present different viewpoints or to amplify a position. Reddit is a common venue for cryptocurrency debates, where users often allege tactics such as brigading, manipulating upvotes and downvotes, deploying bots, and buying high‑karma accounts.

Maxwell is an early Bitcoin adopter and has contributed to development for years. He is often linked with the small block position in the network’s scaling debate. In 2017, during heavy network congestion and rising fees, he wrote: “Personally, I’m pulling out the champaign [sic] that market behaviour is indeed producing activity levels that can pay for security without inflation, and also producing fee paying backlogs needed to stabilize consensus progress as the subsidy declines.”
