I just gave very specific tasks about what and how to check to Youngster.

Also it would be very helpful if you could tell where such links was generated? At this moment if those pages are indexed and redirect is 302 we cannot be even sure does generation bug still exists in vBET, or it is just old bug which doesn't happen anymore but you have already indexed pages. So please tell do you see any page where such URLs are visible in your browser under links. Please check some of your threads, forums, archive, RSS maybe. Please tell do you have any mods which where specially integrated with vBET - maybe there is the issue. Youngster will check it on your forum also (if it will not be restricted), still you know your forum well and maybe you know or suspect where such URLs are generated.
