It seems harmless and encourages clicking, but not everything is nice around the button "like" Facebook, at least for the Independent Centre for Privacy Protection of the federal state of Schleswig-Holstein, northern Germany, which outlawed as a violation of the laws of the Germanic and European Union to collect information about users and transfer them to the U.S. servers.

According to the head of the Center, Thilo Weichert, when a user clicks on the button that comes supply personal information to Facebook's servers.

However, the social network spokesman, Andrew Noyes, said through a statement that the company complies with legislation.

He expressed the button is popular "because people have complete control over how information is shared through it."

The explanation was not enough and the authority of the federal state of Schleswig-Holstein asked to websites based in that state to withdraw before the end of September, the button or face a fine of 50,000 euros.
