many subreddits warn against Dming nudes. there were like 1-2 medical subs that had this problem(perverts) and the mods had to step in to put a stop to people requesting nudes from underage people. prior to the last few years it was largely unmoderated for the most part. then there was a mod(s) that was still a TEEN.

the super strict subs prevented that like askdoc, ask dentisti.
