My thoughts are that once you have received money you have crossed the bridge into a different realm. You have made a conscious decision to do so and should be considered professional.

Having received the benefits of getting paid to fight - you should from that point forgo the opportunity to compete/participate at an ameteur level (i.e. compete at the Ameteur world champs.)

No one forces you to make that choice - but once you have made it live with the consquences / or donate all the money you have received to charity.

If you are serious about your career mange it appropriately and make the right choices - and then be prepared to live by those choices. We can't afford to have flexibility in our rules other wise there is no point in having them - otherwise I may as well go out and groin kick and head butt in my next fight - just becasue it suits me at the time.

Accept the consequences of your decisions and get on with it. NZTBA clearly define your perameters and stick to them.( I think Brett outlined these earlier in the thread)
