I personally know many people who were offended by the warning and ban (I got a warning, grats to all the banned that got 100TP =).
But, Turbine's response was appropriate, though a little slow.
However, why isn't there an announcement and apology about the forum over-policing? If I were a forum moderator and noticed the increased activity about Mabar, I would just lock (not delete) all the threads about it, and post a comment that the issue has been sent to the higher ups and will hopefully be resolved soon.
That's good customer service. That's all everyone here wants.
