I don't know. In principle, as has been said many times, having Facebook or another established social network provider decide what can and cannot be published online is of course not a solution, and non-constitutional. At least Facebook should be required to list, in detail, which accounts and posts were removed, so that there's a chance to appeal Fb's ban. In Germany in particular (but I guess it's no different elsewhere) you get very different opinions on the results of the elections. The AfD party is portrayed by mainstream media as a right-wing and national-populist party; AfD voters will say it's an anti-establishment party, and a necessity when the big parties have almost indistinguishable views on eg. EU.
