It is! It was asked before, leading to this answer (somehow the question in not in the preview, but whatever):
The main issue is that it’s not automatically handled. I had to report a cover before.
Edit: to be clear, it is the responsibility (?) of the person adding the content to mention a problem with the cover, but I can understand people not knowing about that.
Edit2: Huh, I tried to check one of the covers that was previously censored, and it’s not anymore? I wonder if it’s because of the sync functionality that reinstated the original cover. (I’m thinking of 田中~年齢イコール彼女いない歴の魔法使い~ | L30??)
