Every week, Adobe Stock reviews my files, approves them, and rejects them all. However, this week, 15–20 of my files were rejected, and the remaining 50 were not reviewed.
Are you referring to your rejections or someone else's? If you want feedback from the community members regarding your rejected assets, upload a few of them here.
My advice is to be more selective about what you submit to Stock. 5 out of 20 is not a good enough acceptance ratio.
Carefully check your work BEFORE you upload. Compare your best work with other available Stock inventory. For more feedback, post 1 or 2 full sized images here, along with the reasons Stock rejected them— Technical/Quality issues, IP violation, Similar Content, etc... See links below for more details on what's expected.
There can be periods of time when assets by a contributor do not get reviewed regularly. The stated wait time for having assets reviewed can be up to 8 weeks.
