[Solved] I found the base of a duper.
1. My IGN is VoldeBoi33
2. I'm not sure who it was who was duping because the base was unclaimed and I couldn't find their name(s) anywhere.
3. I was raiding their base and as I was finishing up I found a filing cabinet with 2 gold bags inside (both empty) that I had missed while raiding the base.
4. I was stupid and didn't think to grab screenshots before breaking the filing cabinet but i'm hoping the server has logs so that you can find out who was using the filing cabinet.
5. I discovered this today, 4th Jully 2019
A side note: I didn't discover this until after I had taken the items I had raided and mixed them with my own items so if you want me to destroy the items I raided from their base it's going to be difficult as I don't want to lose my items that I have earned legit.
EDIT: Just fixed a typo.
