a member

When I was a pre-teen I joined a group chat online with alot of people with different ages but most of them were 14-17 and one day a guy joined the group and I talked to him but he was giving major red flags of being creepy for instance when I said I'm a girl he asked to see proof as in my face and when I didn't he switched targets to another person in the group and they said no as well. Later that day he asked the group to send nudes pics (TO LITERAL MINORS BTW) and then he sent a video of himself naked a few seconds later he deleted the video(thankfully) though now the members that were online(including me) were traumatized in one case one members hand was shaking since they were only 15 at the time. I got trauma as well and that day my limbs felt weak and my body refused to eat I don't know I just really needed to tell someone about this
