As a Roblox developer, it is currently impossible to keep people from stealing and copying clothing on the catalog.
CLEAN UP THE CATALOG:
ROBLOX’s Image Uploading system automatically accepts pre-uploaded images, which means it has the shirt templates and stuff saved on its database.
With a simple database search it should be able to grab every single shirt with the same template ‘image’.
It can identify the original asset by it’s ID.
It should delete every single shirt / pants template that has been copied except the originals and by the original creator.
(It would identify the originals by the older asset ID) (Smallest Asset ID with the same template)
PREVENT SHIRT COPYING BOTS:
The same way assets get denied if you re-upload an asset, it will get denied if you re-upload it and you aren’t the original creator of the ORIGINAL asset.
