CheckUser is only reserved for an admin in a popular wiki that has lots of editors and editing and had a history of heavy vandalism and sockpuppeting. It’s extremely rare for an admin or a bureaucrat to have CheckUser because CheckUser reveal user’s private information. You don't need CheckUser to block a user; you just need to go to their contribution page and click the block option to block them.
