How do I have no idea what I'm talking about? I quoted directly from the PA regulations on page 1. You can't compete in PA and any federation which does not have a substantially similar anti doping system. According to ASADA, you also can't associate in a professional or training context with anyone who has been banned. Again, the direct quote:
Natural persons shall not be admitted as Members of P.A. if they also, at the time of their application for membership, maintain a membership of or participation in the activities of any powerlifting organisation which does not adhere to an Anti-Doping Policy substantially similar to the Anti-Doping Policy of P.A. Further, any person who is a Member of P.A. and,to the satisfaction of the Board, is found to have taken out a membership or participated as a lifter, coach or official in the activities of any powerlifting organisation which does not adhere to an Anti-Doping Policy substantially similar to the Anti-Doping Policy of P.A. maybe deemed by ruling of the Board to have forfeited their membership and that membership may be cancelled.
It's well known that people tend to leave PA before they get caught, but that's all just conjecture, because it can't be proved one way or another.
You might disagree with other things I have said, but that is just a difference of opinion.
