When it comes to Internet activism and Internet discussion of law in general, you're bound to find a lot of people arguing for "freedom." Freedom to do what they want, freedom to say what they want, and freedom to be anonymous about it. Now, you might say (and many do): "That's because they're all a bunch of thieves and bullies who want to keep stealing and bullying." And to an extent, you might be right. The other reason though -- the main reason -- is that basic rights are almost constantly under attack whenever the Internet is involved. Legislators in Arizona, for instance, want to (and think they can) outlaw obscene, lewd or profane language on the Internet, punishable by a $250,000 fine and up to six months in jail. May I suggest you all engage in a bout of self-fornication?
This Thursday, Larry Sanger, co-founder of Wikipedia, posted a copy of a letter he wrote to the FBI on H-Net. In it, he reports what he considers to be a breach of child pornography laws willfully perpetrated by Wikimedia Commons, the parent of Wikinews, Wiktionary, Wikiquote, and, of course, Wikipedia.
The clearest instances I found (I did not want to look for long) are linked from [the pedophilia page] and [the lolicon page]. I don't know if there is any more, but I wouldn't be surprised if there is--the content on the various Wikimedia projects, including Wikipedia and Wikimedia Commons and various others, are truly vast.
You can see on [the history of the category page] that the page has existed for three years. Considering that Eric Moeller, a high-level Wikipedia manager, is well known for his views in defense of pedophilia... surely the existence of this page must have come to the attention of those with the legal responsibility for the Wikimedia projects.
