Some of my uploads have been deleted

Hi Mods, it seems like a battery of my posts (from a short as a month ago or a year ago) have been deleted for 'low quality' when some/most of these uploads we posted from the original source, however, they were marked as Low Quality here? Can I get a review of these, please? If they are indeed found to be low quality then that's fine, I just need to understand how a photo like this https://wallhaven.cc/w/6oq2wq (source: https://www.flickr.com/photos/nasamarshall/50676102752/) from NASA's Marshall Space Flight Center gets deleted but a photo like this https://wallhaven.cc/w/gjdxoe or this https://wallhaven.cc/w/4y36q7 or this https://wallhaven.cc/w/m92xw8 are considered to not to be the same.

edit: I'll throw In another, this one https://wallhaven.cc/w/pky5gm (source) was deleted again for low quality...that just doesn't make sense to me

Thanks, Szeth

If you look at the wallpapers you have uploaded at full resolution you can see compression artifacts all over them. The other examples that have not been deleted do not have such distortions.

So, noticeable distortion is a key factor when I'm uploading images here on wallhaven and not the maximum available resolution taken by the photographer for the photo itself, is that correct lumberjacck?

Correct. High resolution does not always mean high quality.

Understood. Thank you for your time lumberjacck
