Dan, thanks for bringing this back up -- it hasn't gone unnoticed that this issue is being ignored; it seems to me that getting this resolved should be fairly simple: either changing an option in a configuration file on the server, or submitting a help desk ticket to vBulletin support to look into the software bug.
Since neither of those things has been done, it does lead me to believe the sidebar's intrusion is an intentional decision by the forum management which they have no plans to change. Would be nice to hear this acknowledged and confirmed if nothing else.
