So I editted a body, recoloured it red and stuff. I've uploaded this body multiple times, firstly it said "Fix the frames" so I did. Then tried uploading it again and it said "Inappropriate custom" BUT HOW? LMAO
When frames are out of position, it means the body overlaps into the other frames, half cutting off the body and making a mess.
Realign your body with the starter body template and make sure it doesn't overlap with the other frames.
(you can find the body template on graaldepot I believe)
