how do i stop a mod from temp banning a co admin?

[VBUsers]

ok on my forum i had an issue where a moderator atempted to ban a co admin and was successful. i want to know how to stop this. i know i could add his username to the config.php but i wanted to see another way.

the co admin usergroup is a custom made admin usergroup not the original one. thank you for your help!

I believe the most obvious solution would be to de-mod anyone who goes around banning admins.

And the config.php thing.

[VBUsers]

yes but it shouldnt be possible. and they did it as a test cause they were joking around.

how do i fix this issue?

Check config.php, you can set users there that cannot be changed, banned and that are superadmins..
to change this they will need ftp access... so ofcouse you mod's cant have that...
