Creator agrees that, except as expressly set forth in these Creator Terms, Creator will not use or disclose any User data.
Would using httprequests to get the players device IP and prevent alternative accounts count as any of the points from i to iv?
well, you could.
by connecting an external website to the server and making them go to it, httpservice will be able to request for the IP of the user, although this is probably a bad way of doing it it would work.
You cant access the ip of a user. HttpService is not enabled on the client. That would be a major security flaw if you could. You can only get the ip of the server. So this would not even work.
