I Have a Suggestion for Similar Worlds

Can you add IP checking to accounts to prevent an IP having more than a normal family amount of accounts? Say 7 accounts maximum linked to a single IP. I know this will not help if someone is using vpn, but maybe you can use some logic to check for cross IP's, like if they log in with one IP for user X, then login with a different IP for user Y, and then one day login with the Y IP by mistake, you immediately associate the two and add them together as one IP (Max 7 accounts).

This might help with all the fakes, the bullies, the children on here that just enjoy confusing people.
