Here is a case in point , Terry Mitsos ( retired Aussie IFFBB Pro) going a way,s back, Terry used to be a NABBA athlete , then switched to IFBB , became a PRO , then went to watch the NABBA nationals , NABBA packed a sad when he was seen in the audience and kicked him out , the IFBB heard about the commotion( I think a fight erupted ) and he got in serious trouble for being at a Non IFBB event , I think he got some sort of sanction for his troubles !!!!
