Duping entites

So people can dupe printers,meth supplies, cars etc with advanced duplicator, is there any way other than blacklisting the props?

Remove the tool

No, why would i do that?

Are your mentally disabled or something?

Do you want to disable duping without blacklisting, how you will achieve disabling people from duping those, what kind of magic do you want to do, are you the one disabled?

Blacklist the entities, remove the adv duping or code your own entities so those aren’t allowed to be duped (blacklisting but via code)
