I got a tip today that Stashzilla was duping. So I started to investigate, went to his /home and found the following room:
He panicked when he saw me and tp'd away. I knew something was up.
I checked hawkeye logs and he had made a large number of scs for dragon eggs, spawners and diamond blocks. Also spoke to you and torn a lot.
Went to your /home and torns /home and both are at the same room. Also checked your logs and the same unusual activity came up for you both. I knew you were duping using the scs system but needed to find out how.
Checked all three of your shops, as soon as I entered torns shop he removed his sign and I had to tell him to remove a fire showcase. Investigated his basement to find about 10-15 showcases with dragon eggs.
Finally found what you were doing to dupe items and the more showcases you have with the item the more you can dupe. I have spoken to sawine and the other admins and we agree you have been duping and caught out. You have been perma banned.
