I am disappointed.
I think others deserve to know how this forum works.
It seems that you have just bumped spam links up from the depths. I see no purpose in this unless you are a spammer yourself. other than to assist the spammer.
I put it down to the original poster's ignorance, or perhaps wishing to vent, rather than spam. It is a little disappointing the moderators haven't removed the posts, but I suppose they have better things to do. I wonder if it could be easily automated? It should be possible to just remove the posts with the offending link, but I have no idea whether the forum software can do that, or made to using a script.
