What if I met another guy with my name 'Andrew'
And then I just shouted "IM THE REAL ANDREW"
*Flails arms around*
...
Anyways lots of people have a similar name. There's no chat or pictures of Pizza's ban. Maybe Pizza Man provoked this fella and then he banned him under a different reason. You have no proof of anything here. All I see if a guy with a similar name to another guy.
Also the default build stuff is irrelevant because it's DEFAULT AND PUBLIC. I don't think it matters that he used a default save with his pizza hut. And this is a building game. He's just being creative.
