Spammers are getting more and more creative.

Moderators (and vBulletin) have a number of means to deal with them; however, spammers like to get around those.

There was a suggestion that the moderators re-distribute themselves to help, but even that might not work with PM spam.

I'd go with a minimum post limit for PM sending (say, 1-5 posts before PMs), kind of like with the rep system

Mods, can you get to user Daisy22, fast?
