We're being overrun by spammers!!!!

They seem to be posting thousands of times. All regular posts are going to get lost in their rubbish! I can try and get site like Stop Forum Spam to help. I think they have free plugins. However, Austin or some other admin will have to put it in. Also, I’m not sure if the plugins will remove the rubbish that the spammers already put in. (I think the plugin is more preventing further attack than cleaning up after one.)
