JPG compression artefacts

Hello JP team

Since i had some rejections on a bunch of shots in the sky with jpg artefacts visible i had a look on these pics and found out the pics quality was changed after upload.

First upload shows the pic that was rejected, second the new processed one and the third one shown the second pic after upload.
Whats happening here?
