The German state of Schleswig-Holstein is now challenging Facebook's real-name requirement under a German law protecting a person's right to use an online pseudonym. That law, of course, applies all over the country, so while Schleswig-Holstein is the only state making a run at Facebook now, it probably won't be long before the other German states do likewise. Their commissioner has given Facebook two weeks to comply or face a fine. The fine will be of negligible monetary value considering how much Facebook is worth, but the symbolic value will be far greater.
You remember that Selena Gomez comment I just made? So does the challenging party, the Unabhaengiges Landeszentrum fuer Datenschutz (ULD), a data-protection agency; they cite that Facebook's edits are not adequate to prevent abuse or keep people safe. Facebook, for their part, is pushing back, saying that they already comply with European and, a bit surprisingly, Irish law. Needless to say, the ULD isn't buying the notion of an American entity using Irish law to justify practices in Germany.
That's not the end of Facebook's German problems, as a consumer group, Verbraucherzentrale Bundesverband (VZBV), is suing them over the way their various apps share data. They've already beaten Facebook in court earlier this year, and has taken them to court multiple times over user's address books and the Friend Finder app.
Thus going to show no matter how small you make the world, there are still always going to be some cultural boundaries, and some things people don't want shared.
