if you were banned it was probably from posting unsupportive debate messages on Support Forums , or attacking persons
or even Curezone.
please read the posting guidelines to see some reasons for banning esp the differences between debate and Support Forums ,
and sticking to topics related to forum descriptions.
there are many reasons for banning/blocking.
Curezone actively has Debate Forums
to delve into both sides of issues, to allow others opportunities to address questions ,etc
about validities of some protecals.
we try not to bann unless a person really gets out of control,
and breaks debate posting rules.
to see the rules, look at top of page,
by the forum description, you will also see rules.
you also see rules with every message you post
and by being here as a user ,
you agree to follow the terms of the rules.
hope this helps you understand
what may have been the reasons
behind what happened to you previously
