I see no evidence this actually happened. He didn't seem interested in arguing with you. He also didn't seem interested in finding your channel, he was just saying you won't find him, and had no interest in finding you. I also don't see him kicking you (nobody has been kicked recently). There's also no logs of him saying he would DDoS you.

It's not possible for a tptmp player to DDoS you because they don't get your ip address. The only ip address used is the one for the tptmp server itself.
