Why the censors when rejecting photos do not give any details?

• Stock receives thousands of submissions per week. 
• Reviewers have a Herculean task to keep up with the workload.  
• Adobe has neither the time nor manpower to give detailed feedback to every contributor. If they did, nothing would get reviewed. 😥

Photography is evaluated on the basis of Technical as well as Visual quality.

If you want specific feedback, post the full-sized image here so we can see it.

Adobe Stock is a collection of assets - photos, illustrations, vectors, AI, etc. It's not a teaching website.

You have to submit quality assets. 

To get some feedback, there is this community which can be of help. 😁

Here, you might be able to uncover the reasons behind a photo's rejection by the 'censors' - a better word used in English, moderators.

Adobe does not provide a means for you to dispute the findings of the Moderators; if they did so, surely moderation would grind to a halt as every Contributor would want a second chance to defend their work... However, Adobe has provided this forum for you to receive feedback from other experienced Contributors as to the possible reasons for rejection. Upload a couple of your rejected images here and the community members will provide their feedback. 

The moderators (not censors as they do not censor your assets, but they moderate the submissions) need to work fast, so they have only limited possibilities to mark your asset, when it gets refused. Writing an indepth critique of your assets would cost minutes to hours. And that would assume, that they write in a language that you understand. 

Assets get refused at the first error, the moderator sees. There is no need to continue, but that also would mean, that if you get a marked refusal with "look here is your error", you would correct that and resubmit, just to get a new refusal for a different error, or the same error at a different place.

And a last argument: moderation is not done to make you happy and a better submitter, but to protect buyers from bad assets. As a contributor, you are supposed to contribute assets that comply with all quality requirements that a professional would expect. And contrary to what you say: the web site gives good indications at what to look at. If you do not understand that, you should post one of your refused assets, and experienced contributors will have a look at your asset and give you an in depth analysis of your asset. 

There is no way to reach out to moderators. 

The answer is quite simple. It is not their job to teach you photography or graphic design and they do not have the time to do so. Reading the tutorials on the Adobe website and asking the members of this community can also help.
Post one or two rejected assets and we can guide you through what problems might exist.
