How to "lock" cyberfaces?

Can I ask how do you make cyberfaces uneditable/unopenable? Some of the cyberfaces I made we're being modified or posted on a Facebook group without giving me due credit. I want to make sure these kids don't do it again with my CFs.

I think they make iff files using REDMC.

You can lock it using RedMC if you have a license for IFF editing.
