I have seen a number of spam postings on this BBS lately.
In each case, it is the first posting by a new user.
Perhaps new accounts should be configured for a one or two day "cooling off" period before they can be used to post items?
I just updated vBulletin.Thanks, hopefully that will help. I notice that at least these 2 images are missing:

Maybe some volunteer moderators, who could keep an eye on spam. Kind of, community leaders or something.
