Jillian C. York is director of International Freedom of Expression at the US organization Electronic Frontier Foundation. Some of her articles and a lot of the interviews she has given provide excellent insights into chances and problems of anonymity and pseudonymity on the internet and on closed social network platforms. “A case for pseudonyms” for example explains why being able to use a pseudonym sometimes saves one’s life and often is an important factor to guarantee freedom of speech. “Lieber anonym als verfolgt” partly is a German translation published in the weekly newspaper “Die Zeit”. In “San Francisco Organization Fights For Online Anonymity” by CBS San Francisco Jillian C. York briefly summarizes why she does not like the ban of user pseudonyms by Google+ and Facebook.
