About John Gilmore
Born 1955. John Gilmore is an American engineer, programmer, computer scientist and activist, known for Electronic Frontier Foundation.
Activism Gilmore owns the domain name toad.com, which is one of the 100 oldest active .com domains. It was registered on August 18, 1987. He runs the mail server at toad.com as an open mail relay. In October 2002, Gilmore's ISP, Verio, cut off his Internet access for running an open relay, a violation of Verio's terms of service. Many people contend that open relays make it too easy to send spam. Gilmore protests that Verio's actions constitute censorship, and he argues that his mail server was programmed to be essentially useless to spammers and other senders of mass email. He also notes that his configuration makes it easier for friends who travel to send email, although his critics counter that there are other mechanisms to accommodate people wanting to send email while traveling. The measures Gilmore took to make his server useless to spammers may or may not have helped, considering that in 2002, at least one mass-mailing worm that propagated through open relays — W32.Yaha — had been hard-coded to relay through the toad.com mail server.
Gilmore famously stated of Internet censorship that "The Net interprets censorship as damage and routes around it".
He unsuccessfully challenged the constitutionality of secret regulations regarding travel security policies in Gilmore v. Gonzales.
Gilmore is also an advocate for the relaxing of drug laws and has given financial support to Students for Sensible Drug Policy, the Marijuana Policy Project, Erowid, MAPS, Flex Your Rights, and various other organizations seeking to end the war on drugs. He is a member of the boards of directors of MAPS and the Marijuana Policy Project. Until October 2021, he was also a board member of the EFF.
Affiliations Following the sale of AMPRNet address space in mid-2019, Gilmore, under amateur radio call sign W0GNU, was listed as a board member of Amateur Radio Digital Communications, a non-profit involved in the management of the resources on behalf of the amateur radio community.
