German regulators ordered Facebook to allow pseudonyms last week, a ruling against the social network's "real names only" policy within Western Europe's largest and wealthiest country:

A woman had complained to the Hamburg watchdog after Facebook blocked her account for using a pseudonym, requested a copy of her ID and unilaterally changed her username into her real name. The Hamburg Data Protection Authority said the woman did not want to use her real name to avoid being contacted through it for business matters. Forcing users to stick to their real names violated their privacy rights, it said.

Question is, will this ruling change Facebook's policies against pseudonyms beyond Germany? I asked that of Vaki Zenovka, a longtime Second Life user and IRL lawyer, who gave me a very lawyerly answer. Very short version: Not directly, but Facebook may use this Germany ruling as an excuse to change its anti-pseudonym policies anyway.

Let me pass the mic to Mz. Zenovka:

"On its face," she tells me, "this has absolutely no bearing on Facebook in the US. The German DPA was able to rule this way for a few reasons: first, because pseudonymous speech is permitted by German law; because Facebook was requiring copies of users' ID, which violates German privacy laws protecting passports and ID cards; and because Facebook was actually changing pseudonymous account names to real names, which violates German laws of informational self-determination. The US doesn't have the same laws, so this ruling doesn't have any impact in the US. In fact, this ruling doesn't have any impact outside of Germany, because German laws are unique."

However, she adds, the ruling may change Facebook's policy anyway:

"Facebook has had to change its internal policies globally in the past as a result of European privacy rulings," Vaki notes, "even though those rulings didn't actually affect Facebook's business outside Europe. Facebook's one company, and it's very hard to have business practices that only take effect in one country."

Beyond that, Facebook has been having ongoing problems with its "real names only" policies for years, and thanks to people like Sister Roma (pictured), they've been quietly bending their rules. That's where it could get interesting:
