you can be banned from one forum or from all of curezone, depending on if you just pissed off one forum operator or if you have aggregiously violated the curezone TOS. this rarely happens but does happen. if you continue to make a big stir in one particular forum the forum owner can ban you. you just have to accept the fact that some forum owners will have different opinions than you and in fact may assert opinions you believe to be dangerous and misguided. it happens.
you can always to to another forum like the CureZone Debate forum and make all of the assertions you want about a particular product or device or method and tell us all why its bad and harmful etc. you can even say that you believe a particular forum owner is biased and wrong and promoting dangerous products. that won't get you banned if you do it in the debate forum.
