This makes me suspect that other brush sets have been stolen as well. I believe this website should be taken down, not merely delete the stolen items to dodge the problem.
I don’t think this is a small issue. If you visit the site you’ll see how extensive the damage is. This should not be kept quiet

What’s worrying is that I found at least one brush set there that I created — a set I never promoted in that group — which indicates my brushes have been sold without my knowledge for quite some time. You can tell from the preview still using the old format.
