I do believe this is better suited in Game Opinions and Ideas, moving this for yew ^.^
I see your points, and you do make some good points, but I'm not sure if, given our current situation without the source code, there's a way that we can reduce the sexual activity and naughty shenanigans. We /could/ reword some of the rules, but it's not always going to mean people are going to read them, even though they should. Despite already enforcing that users should report users that do this, many users don't. Either because they don't know how or simply don't want to.
I'm not sure if letting mating in private maps allowed is a good idea though, as a community we want FeralHeart to be, and be seen as, a friendly, safe place for all users. I think if we put that users /can/ mate, but only in private maps, it'll put a bad light on FH. For example, if you're a parent coming to see if this game is nice and safe for their child, I don't think they'd be pleased to hear that mating is allowed.
Although you mean good intentions, I'm not too sure if all of these would be good ideas, sorry ^^ Hope you see it from my point of view x)
