I have reported a few (the ones I could find the source for, using a reverse image search plugin). But it takes ages to image search 100+ models and right now I am too sick to deal with this. Plus it's really not my job. He has been flagged by me and by at least one other author, so multiple times from multiple people. GCTrader should be the one dealing with him.
Anyhow, before I wrap this up, here is what I have found out. It's quite interesting.
Some of the original models are free from Blen***kit (including mine), and some from Sk****fab. Every single model he sells is likely to be a free asset that he found on similar platforms.
I found out purely by chance, because when you are on a model's webpage CGTrader shows you a list of models that are "visually similar", and "his" (my) model was on the list . He probably didn't realize that I had that on both BKit and here, and that's the only reason I caught him.
He is not sourcing directly from CGTrader.. probably cause he would have to pay :)
So again, to those who share any of their models with a free license on other platforms, I suggest you have a look at his collection.
Oh and he keeps on adding new stuff.
