I'm just browsing randomly through Shutterstock. I found this images with marketing labels like "Best Vector Ever""Good Vector""Best Symbol Icon" "Best Seller""Ultra Collection""Exceptional Vector" and a lot more.
Seems to be little unfair practice. Not mention that the same vector is there maybe 30 times with very subtle differences (mostly only different label). I guess this is not generally allowed, but well...

Some examples:
