Edit: While you were typing plugin is necessary for all forums

For someone with a bit more knowledge you could do an SQL query
Unapprove post so you can deal with them later:

UPDATE  `mybb_posts` SET  `visible` =  '1' WHERE  `mybb_posts`.`uid` =THE_USER_ID_OF_THE_USER_YOU_WANT_TO_UNAPPROVE_POSTS ;

Delete posts:

DELETE FROM  `mybb_posts` WHERE  `mybb_posts`.`uid` =THE_USER_ID_OF_THE_USER_YOU_WANT_TO_DELETE_POSTS ;

If you don't know how to perform SQL queries see this thread.
