Sorry to hear about this jhadha, you do great work. Sadly, it's becoming more and more common these days. Dishonest people see these props and decide to try and make a few bucks at others expense. At this rate, it might just reach a point where no one will be able to post there creations without a ton of watermarks.
There is a fellow on Deviantart (Cathorsis) who made great replica ID card designs and shared them with everyone, a few days ago he discovered that his latest creation (a Jupiter 2 card) was stolen and placed for sale within days of it being posted, therefore he removed all of his ID cards an stated that he would no longer make cards for anything, anyone, or for any reason. The reason for this? His artwork was constantly being stolen by our old friend Identityprops ), he finally had enough and deleted it all.
Check out his Deviantart gallery, he left his Jupiter 2 card so it could be compared to the Identityprops version.
