This happened to my adult partner. She was playing OW and someone in that lobby started PMing her for nudes, threatening to disconnect out internet. They ended up ddosing us. Then they were saying how they wouldnt turn it back on without nudes or they would tell her "parents".
Most likely they got our IP when she went into a lobby and targeted due to the feminine handle. All I could think after changing IPs was "this guy must be doing this to children". But this was a few years ago before OW2 was a thing.
