Yeah that’s originally what I thought. Thanks for answering my question.As a user and not part of the Moderation team, I presume it to mean that posting in the thread is a privilege in that one is not entitled unconditionally based on their conduct. Users who troll or constantly make low quality posts (without an effort to improve their contributions through discussion or learning experience) could have their ability to post in it suspended to avoid derailing the thread (something other threads fall victim to for the same reason).
In short: Don't be a jerk, and you're probably fine posting in the thread for honest attempts to discuss..
