These are the most high profile people to be banned who have been identified. There are probably lots of lower profile people who were banned but never spoke up about it and never got called out about it.
An alarming argument has gained popularity among slimeballs where they exaggerate how widespread cheating is and claim it is unfair to ban some people when other people do it, or do it more often. As though some cheating with the black market is more ban worthy than others and that some people should be immune to punishment because not everyone is banned.
