Today again rejected 5 images for the same reason, this time I took AI out of the file names.
Again written to the support and received the answer after a few hours.
Even though this is annoying and not a permanent condition for me, I have to praise the Shutterstock support at this point. They responded to my questions and the answer came very quickly.

With Adobe I had a specific question about a problem with editorials and after 2 - 3 weeks they referred me to the FAQ page.

This time the explanation goes more in the direction of Michaeal's technical text wall 


"....Thanks for keeping us updated regarding this matter with your submissions and for sharing your feedback.

The review process is based on strict guidelines which all our reviewers comply with, but also, it's a subjective process done by humans in which errors can be made.

On the other hand, we noticed the images were oversaturated which might be causing the AI rejection; please avoid the overuse of filter effects for all future submissions. ...."


I love oversaturated images and here so far no problems with the review and now this stupid AI gets in my way. 

Topaz actually DOES inject metadata into the files. They seem to do it randomly, so some files might have it, others might not - a bit of a dishonest tactic. You need to select your files (under windows), right click 'properties', then remove the "title" (which they usually put a compression method directly linked to topaz), and I think it is 'program name' as well (two different fields).

yes, program name shows "topaz photo ai' which is not ai-gen but mis-informed reviews may think it is.

Also, I read this on DPreview :
The new Content Credentials feature attaches metadata to Firefly-generated images to let others know the creator, edits made, and the tools used, what Adobe is calling a "nutrition label" for AI images.

I just followed an Adobe Youtube clip about this "Content Credentials" feature.  It is embedded in Photoshop 25 as a Beta feature and it can be switched on or off through your "preferences".  If it is "ON", the use of generative fill is recorded in the file, even if it is a tiny adjustment like the removal of a logo.

I have done exactly zero AI work, but that AI warning in Adobe stock when I submit photos scares the crap out me. Does sky replacement count as AI? Probably not, but I�m still spooked.
