Staff, Helpers, and VSTF are impossible to block.

However if certain JavaScript codes or scripts are used, all three groups can be banned from chat by admins, since admins have the (chatadmin) permission.

But Staff can unban themselves since they have the (chatstaff) permission.

Chat Moderators and Discussion Moderators can ban Helpers and VSTF, but they can unban themselves since none of those groups have the (chatadmin) permission.

Only admins and Staff can ban Helpers and VSTF so they can't unban themselves.
