Steps to make publish unremovable?
So, even admin won't have the abillity to remove it.
You should elaborate in your use situation with this therefore we will help you better.
I presume you wouldn't want admins to accidentally remove an essential publish that must remain included in the site, just like a 'sticky'. I am no expert in wordpress, but I'd think you can handle that through better permission/role delegation.
or, simply make it a part of your template in some manner.
Whether a publish/text is saved within the database, PHP or HTML files, it's is going to be feasible for someone with admin charge of a website to remove it.
