I've noticed a pattern with Adobe over the years. I make the effort to upload new images... They get rejected for random reasons... I get frustrated and dont upload for weeks or months... I then get multiple sales a day, so I upload more images... Immediately after uploading, the sales completely stop... The uploads get rejected... Round and round it goes. After uploading an image 4 or 5 times it will usually get accepted but for any kind of volume of images, its just not worth it.
Its like its all a lure to keep people paying Adobe subscription fees for their software forever.
Why should a contributor operate at a loss to waste time fighting to upload images into a portfolio they have no control over for constantly falling royalties in return?

Now the Adobe guy will do his helpful thing and ask for me to upload samples of the rejected work so he can investigate and on and on like its been for years yet nothing changes or improves. A Placating game to keep you on a string.

Despite being my top agency for sales, trying to grow a portfolio here just isnt worth the time for so little.

What are other peoples experiences with review rejections lately on AS?

I quit stock a year ago due to relentless and irrational rejections. Now my sales are better than ever at AS, so I try to add new projects and everything is rejected for unknown technical issues. Over and over. As a test I uploaded 2 images with horrid ISO noise and they passed first time.

We do all the work and they make us bleed for the smallest piece of the pie. Doesnt seem worth the investment of time and gear.
