I'm really tired to see this kind of thief.
Microstock is a hard world and we found always thiefs who just open an account and published our works.
In first hand, it's just insane that microstock don't check a portfolio before accept it, or create an algorythm for check duplicate images in their database. With a simple "google search image" is very easier to know the real copyright author name.
In the other hand, i hope they will do more than a simple ban. They had lawer and they could take action more important than a ban.
When we found a thief and we succeed in this case, two more thiefs appears ...
