I accidentally discovered a thief. I recognized some of popular vectors in his portfolio. I read somewhere on the forum that you must be the copyright owner if you want to make complain (maybe I'm wrong). Anyway, I will post links here, I hope that copyright owners will see this.

And many more...

I doubt the original artist will see this, I am writing to the first one, so she can file the complaint, maybe others have more time to contact the rest?

LE: I also wrote a message to the third one.

IStock were excellent at taking these guys down once informed so hopefully if they get one or two reports about this.

The third one (the original artist) replied me, and he reported it. Hopefully it won't take long. I am curios if they just delete one image or the whole port.

Great, thanks for your effort. Well, the entire portfolio is consists of stolen files, with multiple files from a single user. So, it will be ridiculous just to remove one or a few files.

His portfolio is still online and still uploading. But it appears that  few files has been deleted.

More than one agency and not the usual place we'd expect this. Of course Edward Chan, as we've seen before is like John Smith.  Good Luck.

Oh I had to look. 

Chen is the 5th most common surname in mainland China (around 70 million) and 4th most common in the world (around 80-100 million, including all its variants like Chan, Tan, Tran)
