Sorry about my bad Grammer No, that's fine, I still understand your question easily.

Okay. There's no time to check every user on the site. They check IP addresses to see if the the alt account really belongs to the vandal. If there's no vandal, then the administrator won't even bother checking IP addresses. They check when a vandal comes to their wiki and when the vandal created sock accounts to evade the ban. If a user is chaning IP addresses to evade the ban, the location isn't very far from where they are. This makes CheckUser right very helpful and handy.
