I think there should be in game police or FBI in case of scammers cause there will be trolls regardless. What I think how the police should is patrol an area where they think a lot of crime happens or scammers.

Example I could scam Mars, Mars tells the police and they start searching for me. They could arrest me and I may get charged with losing my house may do community work or something. Or if I do something serious I may go prison for three days


Tell me your ideas about this?

I'm  a madara fan. I would say Madara would destroy Itachi, because Madara got the rinnegan and I highly doubt an ordinary genjutsu would work against the Ultimate Prowess (Rinnegan)

Yeah of course we won't have Sharigan as that could be Copyrighted. I mean it as an example but the name is different. Having Bloodlines (descendants)  would be cool.
