Please note that a small "anti-spam" team has been put in place recently to try to keep our forums relatively clean. While we can't prevent the spam from getting posted, we're doing our best to delete it in a timely manner (generally within a few hours at most, we just can't patrol the forum 24/7) and ban the appropriate users/IP addresses.
Given this, it is probably not useful anymore to report the bad posts by PM or to reply to them asking for deletion, unless they've been lying around for more than 24 hours (which would probably mean the team missed it for some reason).
