Extra: Read this before you make decisions. Pizza has been annoying me for a long time. This is certainly not the first time he has made spam before, and I am pretty sure GreenToast himself has seen his immature behavior. The player Shmmacked asked him to stop the spam chat and then Pizza replied with 3 messages of random letters as seen in the screenshot. He has been a nuisance and very immature and for this reason I think he should get a punishment or a warning as seen as fit by staff. Thank you for reading, I just wanted to do this because Pizza has been bugging very many players and he thought he could get away with it, he said it himself.
