I have only been to Sky's Rim only like twice, because the only character that has it's home on top of Assesiants island or something is my anthro dragon Dri. I have seen people raping each other there, but all I do is ignore it. But I haven't seen huge rulebrakers there, yet.
If it gets overboard, then report it, but I recommend you don't tell them, because some of them are jerks and say, "THEH MODZ WIL DO NOTHIG ABUT ET!!!!!" and offend you. It happened to me, always.
