reject for similar issue

I have been contributing since the beginning of this year, and until recently, around 85% of my submitted files were approved without issue. However, for the last 20 days, most of my uploads have been rejected, mainly for the reason of “Similar Content.”

I am a bit confused because even last month, when I created new designs inspired by other images, my submissions were accepted. But now, even if my new designs have only about 30% similarity, they are being rejected.

Could you please clarify the reason for this sudden change? I want to better understand the updated review standards so that I can improve my work and continue submitting files that meet Adobe Stock’s requirements.

Thank you for your time and support.
