Large number of my clips have been pulled down, why?

I have been a producer on Pond5 for just over 5 years.

Yet something happened in the last 48 hours that is inexplicable and unprecedented in my experience.
Somewhere in the neighborhood of 100 of my clips (some of my very best sellers...that have been good sellers for YEARS) were pulled down with NO EXPLANATION.

Many of these are public domain photo manipulations, utilized in After Effects to create distinct DERIVATIVE works.

I have notified the primary admins here with no response or explanation as if yet. I even included the legal documentation that demonstrates the clearance for using government public domain images without restriction.

No response.

I left a voice mail.

No response.

Seeing that many of these are high volume clips, the most obvious interpretation is that I have been targeted for some type of personal vendetta or sales attack. There are thousands of such clips (like mine) all over pond5 and Shutterstock with no problem. Shutterstock is way stricter than p5 on such clips, and they rarely reject, as long as the work is original enough.

Has anyone else had something similar occur lately?

This is very troubling, and could cause up to a 25-30% loss in sales volume. I ask each of you what your response would be to this type of sales loss with no basis in law and without explanation.

how did you notice? I guess I don't track my 'online' # that close. What were the themes of them all? NASA?

Another producer who routinely checks high-selling clips noticed that many of my "regulars" were absent, and he notified me.

I have noticed that some artists on Pond 5 spend way too much time worried about what other people are selling instead of minding their own business. Someone probably complained because you were making $$ and they weren't.

What clips are missing? Subject and sources so we don't fall into same problem.

Check the contract to see if there is anything about public domain imaging.

Don...they are primarily space, satellite, astronaut, even weather footage.
Videostock...the pond5 contract specifically allows public domain imagery to be incorporated into new derivative works.
This isnt a legal issue...the further I look into this and examine which clips were pulled...it appears targeted for high volume clips. I cant believe that I still, as of may 27, havent had a single official communique from p5 after 3 emails and a phone call. I realize yesterday was a US holiday, but this is a serious matter.

no response yet?

I understand your frustration but there is no personal vendetta against you or anyone.
The clips were taken down while we investigate an issue with those clip and it just coincided with the Memorial Day holiday.
We will be in touch with you today.

Thank you, curator2. As I said earlier (in my emails to staff) in the worse case scenario, if there is a stray logo somewhere, that clip could be marked Editorial/Documentary use only, but to remove a legitimate derivative work (of which there are probably tens of thousands, if not hundreds of thousands on pond5) then that unfortunate witch hunt will be a real tragedy in our business.
