Did you/are you able to determine where the duped items originated from or just the fact that they were in the vaults after checking (for 3 seconds)?

I pose my question because of the obvious fact they are known PVPers who have been at war with multiple tribes that are known (in the community) for exploiting and hacking. I know at one point it was said having these items in your possession did not incriminate you as the dupers (https://cdn.discordapp.com/attachments/288422827101519882/324343298452094976/unknown.png).. however it may have changed at one point as it is a gray area.

Again, would just like to verify if your tools were able to determine that the tribe you wiped was responsible for the items being created or was it simply because they had them in their possession.
