Dead NT Wiki pages

Soooo I just like to press "Random pages" and see what comes up just for fun or if I want to edit something, and sometimes I stumble over a really dead place, like for example TTL http://nitro-type.wikia.com/wiki/The_Typing_Legion . The place is dead, the team is gone and replaced, so I just made some minor edit that says that it was deleted and stuff. What do I do? I know people like me can't delete it (I think only mods/admins can, I'm not sure) so should I just report it to some admin every time I see outdated things?
