Honestly, there's no other reason for me to ban him. In this story, a lot of mud was thrown at me, and I'll be cleaning it off for a long time. And it will most likely put an end to my organizing efforts, which I was well aware of when I banned Rebell. And now I have to deal with the Thinkeer case, and if he gets banned, my relationship with the Chinese, which I tried so hard to build, will be damaged. I can't prove that I don't have any dislike for Rebell. But banning him is not beneficial for me. In general, banning anyone is not beneficial for my tournament.
As for Black_Knight, I don't know, maybe he was cheating before. Or maybe Vitalik was cheating, but some time passed, and he was accepted back into the tournaments. In my opinion, everyone has a chance to make amends.
And by the way, the ban was issued based on a vote by the judges; I didn't do it alone
