Real easy.  Mr. Moderator, just change to a "Restricted Membership". 
That way when anyone wants to join the group you have to approve them 
before they can.  If those morons can't join, they can't post.  
Problem solved.

I had some of the same problems in the group I moderate, Drumzilla's 
Lair.  Restricting the membership cured the problem.  

Try it, it works.
