#1. Chris Jericho
Perhaps the most recent name to be banned by WWE, since reports now suggest that the commentary team are no longer allowed to refer to his move as The Codebreaker, but now they aren't allowed to use Chris Jericho's name either.
According to a report by The Wrestling Observer, it appears that the current AEW World Champion is not allowed to be referred to by name on WWE TV anymore after the company failed to mention him at Clash of Champions. The Miz took on Shinsuke Nakamura as part of the show where he could break Jericho's record and become a nine-time Intercontinental Champion, but when the commentary team talked about The Miz breaking the record, they only stated that he would, not that it was still held by Chris Jericho.
Y2J is one of the greatest wrestlers to have ever stepped into a WWE ring and he still holds a number of records, so it will definitely be hard for the company to erase him completely, but the fact that the name of his finisher and his given name have now both been banned by WWE, means that he isn't expected to make his return anytime soon.
