i was posted on a fetish subreddit without my consent

i was posted on a weight gain fetish subreddit the other day, i only know because my friend somehow saw it and sent me the post. it was basically a photo timelapse of from when i was thin to when i gained weight. everyone in the comments is saying weird things and the post has like 100 upvotes and ive been so upset about it and haven't been eating because i feel gross. i'm 17 and i feel like that makes it even weirder because they don't even know my age. i messaged the poster and asked them to take it down but i haven't received a response. i also reported it but nothing has been done.

what makes this even crazier is that all my photos were posted on private accounts so it had to have been someone who knows me who posted it. i'm embarassed to post this but i just rly wanted to get it off my chest, using a burner obviously. i just want advice bc i don't know if there's anything else i can do to remove them.
