It would only affect sites with more than 100,000 registered users, bring in revenues above €500,000 per year or receive press subsidies larger than €50,000. There would also be exemptions for e-commerce sites as well as those that don't earn money from either ads or the content itself.

If passed and cleared by the EU, the law would take effect in 2020.

There are a number of concerns about the draft, though, and many revolve around those exceptions. They're meant to give young sites a chance to grow before they police their users, but they might actually protect the communities most likely to engage in abusive comments, such as hate groups that may have small bases and no advertising. There's even a potential conflict of interest -- the law might protect the ruling party's junior partner in government, the populist Freedom Party, from having to curb hate speech on its sites.

The EU might balk at the law, too, as it could punish European companies more harshly than in their countries of origin.

As always, there's also the simple question of privacy. While requiring names and addresses could discourage harassment and hate speech, it might also discourage people from coming forward with insightful stories and opinions. Moreover, this would turn sites into veritable gold mines for hackers -- if they could breach a database, they might swipe personal information for thousands or millions of users. Simply put, there could be a chilling effect on freedom of expression even as Austria attempts to preserve it.
