Context is everything
It's basically a give and takes, depending on how people play it will dictate how hard NQ will bring down the law. Obviously, there is a minimum legal requirement put on them by the law in France, child porn and death/gore is definitely going to be a bannable offence.
If a bunch of players decide to be provocative and push the limits there will be a push back, if players are more chill and create some risqué content but keep it to themselves in their own bases then It will be fine, but the same content erected at the ark ship might be breaking the rules.
NQ has been very clear, this is a game for adults, children are not allowed.
