Facebook “Like” button and promotion guidelines

Facebook: the universal platform for individuals and businesses. However there has been much speculation about how much of your information remains confidential and how much of it becomes freely available to the Facebook Headquarters and others.
Those using Facebook in the northeastern parts of Germany have been warned to avoid the “Like” button. All government sites within Scheswig- Holstein, (the northernmost of the 16 states of Germany) have been requested by the Independent Centre for Privacy Protection to dismiss every Facebook plug- in. If they do not comply with this request, they will possibly face a fine of about EU€50 000.
This request comes after a press release announced that by pressing the “Like” button or becoming a fan of a page on Facebook, Facebook users become victims of infringement laws. If a Facebook user takes this action their profile and all the information on it becomes available to the Facebook Headquarters in the United States. Germany’s online privacy laws do not under any circumstances support this.
German government websites have removed the “Like” button however other suggestions have been made, such as avoiding Facebook completely. In the mean time, German online authorities are working with Facebook to develop a common understanding and set of privacy issues.
