That actually looks like a it is a bug or a configuration issue in the forum software. If the post was removed/moved to a private deleted folder or soft deleted in place, the thread should go back to its previous state.
There is a current list of posts by hhok2008 that show up under the "Last Post" column, but when viewing the thread they don't appear. This is actually the first time I have seen this occur with a forum using VB. Perhaps those posts were attempting to exploit some bug in the script that is causing them to still show up in the counts and the Last Post list.
If you are learning PHP, developing PHP code, or debugging PHP code, do yourself a favor and check your web server log for errors and/or turn on full PHP error reporting in php.ini or in a .htaccess file to get PHP to help you.
