Considering how strongly creating multiple accounts is discouraged, that should be sufficient reason alone to help users sort out their issues. However, I stand by my previous statements, a single site admin for such a HUGE site, with the traffic it gets, is simply not sufficient. Unfortunately, I don't think any of the moderators are familiar with the vBulletin software (no offense, just sayin'!). Even for a small site with only a couple of hundred users a single admin can have trouble keeping up.
