Came to the topic late but… There are instances where stolen work go through it all and won’t get caught.
There are instances where “creators” upload models that were previously deleted and posted in a new account as a “new model”.
There are instances where makerworld turns away their faces because that “creator” brings them flow.
There are many cases that are being reported and not answered, that’s not new.
I hope you get it sorted out because it sucks, i know.
Best of luck
