Grams (search)

In June 2014, Grams released Helix and Helix Light, a market payment service with an integrated bitcoin tumbler. The site was also available on the clearnet via Grams Flow. Due to the enduring popularity of the site, and relative ease of replicating the first few digits of a .onion address, a number of illegitimate copies of the original Gram hidden service have been created. Like the Helix scam, these sites defraud unsuspecting visitors of any money or personal details entered on the fake site or fake marketplaces it linked to. == Owner ==

On February 6, 2020, the FBI and IRS arrested an Ohio man, Larry Dean Harmon, who they alleged was the operator of Helix and Grams. Helix was said to have been partnered with AlphaBay, an illegal darknet market shut down in mid-2017. Harmon pled guilty in August 2021 and agreed to forfeit 4400 bitcoins as part of a plea deal, and faced up to 20 years imprisonment. Harmon's sentencing was initially deferred while he worked under a cooperation plea agreement, and finally in November of 2024 he was sentenced to three years in prison. == References ==
