Are the spammers getting tired or something?

Hmm. On a slight tangent...I seem to recall having dropped a link to a group of people I know to one of the articles in the forums here (I forget which one offhand), but I don't think there were enough of them to cause a surge. But they would show up as 'guests', wouldn't they? And, is there a more proper way of making referals like that than linking to the forum thread?
