If it comes from someone that is registered on the forum, I, or one of the other moderators (Ucantcme , thegoldpt) can put a ban on their username.
Also, we really just can't take your word for it as some forum members would have us ban anybody they don't like or didn't agree with their opinion. Almost 100% of the spammers and someone who would send PM's to members like your talking about are first time users with a posting count of 1 or 2. We;ll take a look at the posters background and if you could, highlight all or part of what they sent you so we can see the kind of message your talking about. PM one of us and we'll take it from there.
