It will continue to be a problem for moderators because of the way they moderate and the terms they outline to moderate by. They leave gray areas for things that are against the law but that they feel are perfectly ok, but not for other things that are against the law that they feel aren't. They don't provide clarity about the law in their locality, and they don't always stick to their moderation in a way that would make it the same for all users and that's the problem. Additionally they don't want to be blamed for anything or take backlash for anything so they overlimit some things and under limit others and pretend their hands are tied about both.
