There is a lolicon scanation site set up like a blog named Little White Butterflies that has been removed from Google’s search engine. It was from an anonymous person with a Google link to ChillingEffects.org explains the request when you search for the site. From my knowledge this has never happened before and this contradicts all of Google’s past behavior. Google is in conflict with China over censorship and so far did a lot to help find middle ground. Because the request came from an activist likely, they surely had good intentions. The site that this involves does know the laws that relate to this and even pointed pointed out that Chilling Effects hasn’t fully kept up to date to how the laws for this are set up. “This definition does not apply to depictions that are drawings, cartoons, sculptures, or paintings depicting minors or adults” which can be seen here. The link is to the current version of Title 18 of the US Code passed by Congress in January 5, 09. Even if you don’t support such content or media, this is still censorship and it is subjective.
One problem which was stated by co-blogger EhNani is fighting back will only draw more attention to the issue. With more attention you’ll have more coverage from average people who won’t understand the whole scoop of things, its culture of origin, and context. The best a site can do is privately discuss reconsideration with Google. Perhaps this entry itself isn’t helping matters.
Edit: The sites content could still be considered illegal for being obscene, see Raiga’s comment bellow.
Edit: Decided to include the link. The linked page is fine, but the rest is not safe for work or school.
