Suspect Members That Spam

[unps]

Now I don't have this problem right now but I'm asking just in case it ever becomes a problem. My question is... Is there a way to screen private messages and emails by members that I suspect of spamming other members to come to their site? Is that even considered spamming?

Anyone?

I appreciate the help! Thanks!
