Ok, since I like this thread and the comments added from Stoebi. I will assist you in the how to prevent mods from using the clear all or "Every" option.

As you know, a moderator using the added code provided, can ONLY clear bans from THAT thread that they are allowed to moderate in. Should they "try" the "every" option, it will fail. This was the design of Stoebis moderator code.

So should you STILL need to feel you want this blocked. Here is the code.
In the Style Manager, Edit SHOWTHREAD

Find:
<if condition="$show['btu_canban']">

Replace with:
<if condition="$show['btu_canban'] AND is_member_of($bbuserinfo, 6)"> 

The "6" is the default for the admin usergroup, meaning only anyone who is in part of that group, will be allowed to see those 2 options in the drop down.

Problem solved.

Hope that will assist you some. =)
