I was nearby so this might sound weird coming from me but I've not seen the dupe at all.
Anyway, you're gonna need to...
A use the template
B show us clear proof
C show us proof of WHAT Dupe was used.
D proof that the dupe wasn't damaged.
If a dupe gets damaged and thanks to that it becomes prop block it's their own fault. Not the dupe owner's.
If you want to I will also move it to the report abuse section.
Good luck!
