Restricting Admins

[unracer]

Hello all;

Big issue for us:

Several admins on my forums; one of whom decided arbitrarily & without consensus, to delete several THOUSAND posts from one user.

This is not good - we have some division as a result etc.

As the only one with access to config.php, it there a snippet I can insert to restrict/prevent his user ID from these mass deletions? Or similar file?

I'd ultimately only like to restrict "deletion of posts" by this !

Thanks
