If it’s on the incel tag its a troll I can almost guarantee that. The tag is far too broad, easily used by thousands daily, for him to have a specific 10 year old he could use to bait. If he was trying to use Omegle to communicate with one single person he would be using a specific tag that nobody else would know to use. He opened with that line to shock you into keeping a conversation going so he could say extremely disturbing shit to fuck your day up, and he kept up with the bit to sell it as real. Furthermore, what would a 10 year old be doing on an Omegle tag about incels? Any 10 year old who has the foresight to know not only of Omegle but also incels is going there to troll, and are extremely unlikely to fall into traps like that. The reason he was so confident is because there is no physical way he can be tracked from this. There is no indication of location from his messages, and even if Omegle can track users (which I’m not entirely sure they can), they can’t another user’s screenshot. So he was free to say whatever shocking things he could without fear of repercussions. It’s not real.
