Although it would be a solution its never going to happen unless vBulletin.org hire someone, the moderators here get paid nothing and are voluntary,
most
of them have lives too and don't have enough time to check every modification.
Anyway if the person who created the script cannot spot one how do you expect someone who has never seen the script to have a better chance at finding it!
Also you have to think that if a moderator does check it and gives it the all clear and later an exploit is found and forums get comprimised, it puts alot of pressure on vBulletin.org and on the moderator, possibly legally too.
