Almost a month ago, I received a notification from Shutterstock that one of my images was flagged for a copyright violation and my account was being suspended. They offered a few methods to supply proof that I'm the copyright holder of the particular image. Very quickly I sent the evidence to them and received a response that my case would be escalated. Since that time I have received no further communication, and all of my images have been removed from the site, and I can't log in to my account. They have ignored the many e-mails I've sent. It should take no more than 10 minutes to look at the evidence I submitted and conclude my account should be reactivated.

Has anyone been through this process before and what was the outcome? There was also no indication from Shutterstock why they thought there was a copyright issue in the first place.

Yes, I have the raw data.

I submitted a screenshot showing a series of raw files of similar angles of the same subject. My point is that there has been zero communication. Even if the proof I submitted was not satisfactory in some way, it would take  less than a minute or two to make that determination and respond. However, I believe I have demonstrated clearly that I'm the rightful copyright owner.
