Avatar Moderation is baffling me

(this is the image I always use)Hello, I just made my EA account to play Titanfall 2, but when I went to add the profile picture that I use for almost everything else, it got rejected. 

Just as a quick test, I decided to upload an upside down version and that got approved, and if I upload a version with no lines and shadow, it also gets approved, so I'm wondering, what is so bad about it being right side up with lines in the background and a shadow?
