Might be a bit easier for ms who has accounts tied to consoles though.
If a person logs in from a different location elsewhere in the world in a very short time frame(it a distance that it would be impossible for them to travel physically). IE Someone's IP shows they are in Florida then 5 minutes later it shows they are logged in with an IP address in New York.
