A.I failing at recognising if art is explicit or not

I am a digital artist and I have joined multiple art servers and communities since my joining around 2018. Since then I have been posting my w.i.ps (work-in-processes) and my finished artworks onto these servers. recently, some of my artworks have been scanned by the A.I as "explicit content". I don't understand, I am a 14 yo who never draws gore, nsfw or lewd. the first piece was around a year ago, I don't really remember that one. However recently, I drew a piece of Jiro from mha as fanart, the pose was the character sitting next to a wall, she wore a long sweatshirt and a decent-lengthed-not-showing-anything shorts. HOW TF IS THAT CONSIDERED EXPICIT? Please Discord, fix your fcking a.i's
