Fictionhunt.com: To remove all stories until they are given full permission by each author.
EDIT: The site has been closed, thank you for all your support
EDIT: For the moment the site has gone. I hope that it remains this way, but I believe this campaign was a large part of it, so please do keep adding your signatures, because I am sure this is not the end of this.
The creator of this site has taken it upon himself to copy fanfiction works from ff.net and host them on his own site, without getting any permission from any of the authors of the stories. And having been asked nicely to remove the stories has flat out refused. He has agreed that if enough people want him to remove stories from his site, then he will reconsider his position on the matter.
(EDIT: He has now agreed to remove stories on an individual request basis. And he has changed some of the formatting of the website so that it primarily just acts as a search engine for stories on ff.net; however, he is still refusing to make any attempts to ask permission from the authors, making his site opt out, rather than opt in, as it should be)
