Frequent "Similar content already exists in our collection" rejections — even for unique images?

Hello everyone,

This month I’ve been getting an unusually high number of rejections on Adobe Stock with the reason:
"Similar content already exists in our collection".

Here’s an example of one of the rejected images:
(attached image: two people on stage, unique composition, studio lighting).

I carefully checked both my own portfolio and existing Adobe Stock content — and I don’t see anything that closely resembles it, either in composition or style. It seems like these rejections might be automated, possibly by AI moderation?

I have a few questions:

1. Has anyone else experienced a sudden increase in this type of rejection recently?

2. Do you have any insights on how the system determines “similar content”?

3. Could this kind of rejection impact the account’s ranking or visibility long term?

Any tips on how to avoid this issue in the future when working with AI-generated images or series?

Would really appreciate your thoughts and shared experiences. Thanks in advance!
