Fakku

Fakku (styled as FAKKU!, or simply F!, from the Japanese loanword for fuck: ファック) is the largest English-language hentai publisher in the world.

Fakku was originally an aggregator that provided users with scanlations of adult manga and dōjinshi from Japan. At the start, the content was uploaded exclusively by the site's administrators, but later these privileges were shared with the community, allowing for translators to have their work seen by a much larger audience. However, at the end of 2015, Fakku made the transition into only publishing officially-licensed hentai manga.

Fakku and its creator Jacob Grady have a known relationship with Danny Choo, TV personality and blogger. At Anime Expo 2010, 2011, and 2012 (in Los Angeles, CA) Jacob and Danny hosted community meetups that attracted large audiences of fans and users.
