#3 Jeff Jarrett
Jeff Jarrett is one of the few people that are still considered as persona non grata in WWE. He managed to achieve this status by doing several things that must’ve irked WWE to no end over the years. First, he’s alleged to have exorted WWE of an estimated $300,000 from Vince McMahon in 1999.
Secondly, and more importantly, Jeff Jarrett was the founder of and served as an influential force in TNA Wrestling/Impact Wrestling. In a way, Jarrett was the one who founded the promotion that served as the closest thing to direct competition for WWE for many years.

And as you know, dear reader, Vince McMahon and his family despise competition and see red with anyone that tries to – in his mind - put his family out of business.
In this respect, you should never expect to see Jeff Jarrett in WWE ever again. The man has effectively blacklisted himself by WWE through all of his backstage dealings and business decisions to the point that enough people in WWE consider him their true enemy in the professional wrestling business.
