Alphabay

AlphaBay (often misspelled “Alphabay”) — what it is, and who ran it

AlphaBay was not a person. It was a large darknet marketplace—an illicit e-commerce site reachable via anonymity networks (notably Tor, and later also I2P)—where users traded illegal goods and services, especially drugs, stolen data, malware, and forged documents. (justice.gov)

Key individuals commonly associated with AlphaBay

• Alexandre Cazes (alias reportedly “Alpha02”)
  U.S. authorities identified Cazes, a Canadian citizen living in Thailand, as AlphaBay’s creator/administrator. He was arrested on July 5, 2017, and was found dead in custody on July 12, 2017 (reported as an apparent suicide). (justice.gov)

• “DeSnake” (pseudonym)
  Media reporting and later accounts describe “DeSnake” as AlphaBay’s former administrator/security specialist who claimed responsibility for relaunching AlphaBay in August 2021, using cryptographic signatures (PGP) to support the claim of continuity of identity. (wired.com)

If you meant “Who is Alphabay?” as in a specific account/artist/company using that name, tell me where you saw it (e.g., X/Twitter, Instagram, GitHub), and I can disambiguate.
