You got a point. There are some wikis that when a user commits any of the gravest offenses--usually vandalism or spam-only--, then that/those user/users are blocked at once without warning. Usually the block ranges from like 30 days or so to infinite. One example would be the Five Nights at Freddy's Wiki. The admins there infinitely block without warning to those who will be caught vandalizing.
