You must take a precaution for Design Theft!!

I design for hours every day and continue my sales by following every rule. Thieves steal our designs and sell them on adobe with exactly the same images. I myself can find thieves with "Find Similar" search. So why can't the teams that review the designs do this? For this, a very simple software can be made with a software that scans for previously shared designs. How can you allow this theft? They stole all designs and 3 separate accounts uploaded them exactly the same. And you confirmed and shared them all. Their designs are stolen and shared by other designers in their accounts, except for me.
A solution should be found as soon as possible. We make designs everyday with our waist and neck aching, and a thief can steal, load and sell them. Those who examine the designs approve and publish it without knowing it. Do I have to search every week to find my stolen designs?
