Ban

A ban was a way to prohibit something.

History
Senior librarian Ms Millicent Davies banned the Ninth Doctor from the York Central Library after she caught him defacing biographies with a hand-held electronic 'eraser' device. She also applied for the Doctor to be given an ASBO so he would be banned from all UK libraries. (PROSE: Have You Seen This Man?)
