My main evidence here is what he said immediately after spawning, followed by nearly debilitating uncharacteristic lag that stopped the instant I banned him - so I'm going to just post the relevant console snippet.

All IPs other than Pineapple's and my own have been redacted. The lag started almost immediately after he said "k", and stopped at exactly the same time the first ban got through.
Discuss.
