I also don't see the link between your infractions and the overhaul that was done on the boards.
You can see the announcement about the changes
here.
I think it's probably a good thing that the substance abuse board has gone, because small quiet boards that were within another board tended to be visited very infrequently by people both seeking and giving support, so having threads related to substance abuse in the busier main boards means that people get more support more quickly.
Of course, you are entitled to disagree with that; I myself was and still am strongly opposed to the Moving Forward board being removed, but the decision was done through a democratic process and I think it's right that we went with what the majority wanted.
