I really don't even need proof.
Just join his server.
He decides "OH, I'M THE HOST SO I MIGHT AS WELL BREAK MY OWN RULES FOR THE HELL OF IT!"
He first starts off breaking the rule of buildkilling. I'm trying to build in peace while he keeps shooting at me.

So what's his excuse?
"it's a joke lol"
Grow up, Aes.
