Normally, and more if you are a mod before, you need to know it’s necessary to ask permission to the artist to post his/her art.
 
Or at least, give notice about the upload.
 
Rule #1 point 2
 
 
1 Respect artists and their artwork
 
Do not upload artwork that has not been publicly released, or is intended to remain private or restricted access, without permission from the artist who made it. This includes paid content, such as Patreon-only images or images from an art pack or folio.
 

 
More because you can say me in the chat you want to upload this to here.
 
And I react like this, because I hate myself and I’m the most critic with my proper artwork, and hate all that not have a minimal amount of likes/favs, in digital draws.
 
Say that, I will ask for a DNP Artist only
