How do I hide the rank for a few users?

I posted this question over on vbulletin.com and it was suggested that this is probably going to require a plugin and I should ask over here.

I would like to hide the rank for our admins and mods in the postbit.
Basically, our ranks are tied to our usergroups and most of our users are a part of 2 or 3 of them, which works great. But, our admins and mods may belong to 6 -10 usergroups for one reason or another and the ranks are displayed for each, which doesn't work for us.
I looked at a if condition in postbit but can't get it to work. I'd like to be able to exclude based on userid (ie. 3,5,20,233,etc)

Thanks for your help!
