What a stupid idea. If the municipal authority was able to deny people access to Facebook or from mentioning their name in a derogatory sense AT ALL, there might be an argument.
Spamming a moderated page is something else. It'd be primarily used for announcements, and while they might allow feedback in general, that can always be temporary. They can set it to no-comments if they wish.
If they're going to enforce something to say members of the public are able to say anything wherever they like, if you go and spraypaint the town hall with graffiti, you can't be arrested for that either? Freedom of expression is an important right, but saying no to spam and abuse is not curtailing someone's right to blather on their own platform/feed/whatever.
