i don’t know what to do

hi. i wanted to see if anyone else has gone through something like this and how they handled it.

today i found out there's a subreddit where people ask for pics of girls from my city and even sell their pictures without consent. someone told me my name showed up there, so i went to check and found like four posts where they were asking for pics of me, and comments like "i have them" and stuff like that. implying they had some. when i was younger (15/16) i did send some photos to an ex, but that was it. recently i also found out that a "friend" hacked into my snapchat, took my photos, and started selling them. at the time i didn't want to take legal action and just cut contact, but now that i saw this, i'm scared he might've been the one who spread them.

seeing my name there gave me so much anxiety and i just froze. i'm an adult now and i don't know how to proceed. i’m not sure if i should file a report, ask for help first, or try to find out if the photos being shared are actually mine. but all of this scares me and i honestly don’t even know where to start.

has anyone gone through something similar? what did you do?

if anyone has been through something like this or knows what steps to take, I’d really appreciate any advice.
