There was a situation at Hardcore Justice where PJ Polaco (Justin Credible) was asked to remove his shirt because it said his name and had an ECW logo on the back. Credible wore it during his entrance but was told by security, who was told by officials, to remove the shirt.
Word is that Credible had to use his real name because an indy wrestling promoter with a grudge had his girlfriend trademark the Justin Credible name. WWE does not own the Credible name.
Credible has issues with many promoters and fans these days. There are also fans who claim they are owed money from PJ for tickets purchased to an event which never took place. PJ claims he's never seen any of the money and that someone opened a 'fake' Paypal account under his name. The only problem with that is Paypal requires a user to enter their own personal bank account info. to create an account. Weird.
