They don't like my moody B+W photos?

Since my previous post on June 29, I've experienced a parade of rejections without a single acceptance (all of my photos, they have not attached any AI generated creations). In an effort to stay with 50 waiting images allowed at any given time, I bid farewell to some of my AI stuff, and opted to upload my own photos.

While I understand the importance of guidelines and rules for stock photo acceptance, it's perplexing how they manage to find time to reject my photo submissions but not a moment to accept them. Is there a preliminary AI scan followed by a second, possibly human, team for approval?

If anyone is familiar with their mysterious process, I would greatly appreciate some insight. Thank you kindly, fellow curious minds!

The quality guidelines are clearly defined. 

Requirements for contributing photos and illustrations to Adobe Stock

For instance, here is stated "Do not convert to black and white".

It's not about liking a photo or not, but rather determining the commercial usefulness of a photo.  Some of my favorite photos make for terrible commercial assets and vice versa.

Aside from having them accepted, I have a few in my portfolio and they just don't sell.  In fact, b&w images perform poorly on all of the stock platforms I submit to.

Good luck with your future submissions!

Adobe stock no acepta fotos. que le hayan manipulado los colores, en este caso está en blanco y negro, la imagen debe estar en su color original.

Your moody black and white images are quite nice; but Adobe's guidelines specifically preclude submitting B&W. Reading all of the help pages will improve your chances of success in Adobe Stock.

Converting to black and white can be done at the customer side, so that's listed as one of the donts in the instructions. But looking into the first image, I also suspect the asset to be underexposed, which is also not allowed. 

Your second also exposes sensor spots: , besides not having much in focus.

Your third also exposes artefacts due to overprocessing: 

Post the pictures on social media, and you will get manny likes. They are not usable for commercial applications, except if you submit near flawless colour pictures.
