one of the cases involving plagiarism on flickr:

Photographer Gets Plagiarized then Censored

Rebekka Guðleifsdóttir is heralded as one of the top photographers on the photo-sharing site Flickr. Guðleifsdóttir, a native of Iceland, is well known for her self-portraits as well as her surreal landscapes.

However, she recently discovered that a photo printing site had not only posted several of her works under a false name (Yahoo! Cache Version), but was selling prints of those photos in their store. A search through their Ebay store turned up approximately £2,500 (about $5,000) in sold prints, all with her work.

Seeking repayment, Guðleifsdóttir turned to a local attorney who sent the company a stern letter. The company removed the works from their site and then fell quiet. No future correspondence was returned and Guðleifsdóttir, a single mother and a college student, was left footing the bill for the lawyer.

Understandably upset at this outcome, Guðleifsdóttir vented her frustration in her Flickr account.

The story struck a chord with the Flickr community. It quickly reached the front page of Digg (earning over 4000 Diggs) and the entry generated well over 400 comments.

However, the original entry was to be short lived. Only hours after it hit the front page of Digg, Yahoo!, who owns Flickr, removed the post. According to Guðleifsdóttir, Yahoo! cited alleged terms of service violations.

That, in turn, has kicked off another storm of controversy with many criticizing Yahoo!’s move as censorship.

But in addition to being an interesting case of plagiarism gone awry, the story also serves to illustrate many of the challenges that arise when trying to protect your works on the Web.
