Not sure how to handle this, was trying to find an admin to send it to directly, but maybe you can help me.

I am receiving spam private messages from a user.

Every 5 minutes this person is sending me a message about another forum. Is there a way I can ban this user from sending me messages or get their message privileges revoked or something?

This is the person sending me the messages: http://forums.teamestrogen.com/member.php?u=9036

Thanks.
