Bizarre.  100% stolen images. (lots from Shutterstock)

Usually, if you try selling on the same site you stole from, they notice.

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 ...

Vectors also, and I doubt it is the same person..

Good for you for discovering this! It looks like their port is removed.

you said: "or create an algorythm for check duplicate images in their database"

almost every site i work with does not check for duplicates except for videoblocks, and they only go by filename and file size, and probably only for your own account.

there are algorithms to check for duplicate content. two famous ones are SHA1 and MD5. they are easy to use and free. I wish stock companies would use them. they only detect exact matches of the actual files.
