Hiding a design element from a single user

[static-skillz]

One of my staff members on my site is asking me if its possible for me to hide his post count and a few other things from all members of the forum, and I was wondering if I can use conditional templates?

I know you can use: <if condition="$vbulletin->userinfo['userid'] != 557"></if>; to hide the information from that user id, but would it be possible to hide an element for a single user, for all users?
