Are you running the "Experimental" build server side? You want to use the regular Procedural or Navezgane option server side if you are not on the beta build.
Mod ID's are generally listed on the workshop page, if they cannot be found there, you can copy the page link and the 9 digit number in the mods link will be the Mod ID!
I have not heard of this specific issue, I know you mentioned you are not the owner, however do you know if other players on the server are experiencing this?
We have a wiki page regarding this, it is a very simple process. A video should not be necessary.

Is this for an ARK server? You are able to disable PVP in the Modify Config Tool found in your control panel. Look for the "Disable PVP" option and check the box off, then scroll to the bottom of the tools pop out window and save the changes made.
