An unexpected release of Shoutbox. It seems that spammers have picked up Shoutbox and now recognize the post method and are actively spamming on it.

It seems that I forgot to add an check to prevent anonymous users from posting in Shoutbox when they do not have the correct privileges.

If you are experiencing a spam problem, please upgrade as fast as possible:

This upgrade will only fix the problem from spammers being able to post even when they do not have the privileges for it. If you allow anonymous users to post spammers will still be able to spam on your installation.
