Ratzinger, take it to PM. The mentors weighed in at the beginning of that thread, made the limits on the discussion clear, and you took the discussion beyond those limits. Period. Warnings are NOT infractions. Since you've already publicly aired that you received a warning, I'll just remind everyone that warnings (with no infraction points) are just our way of informing you why your post was deleted (or moved, or reminding of the rules, etc.), just like it says in the PM that is sent with the warning. It also creates a record of the warning for the other mentors to view, so we all know what action was taken and exactly what was said in the PM from the mentor. That's all it is and there's no reason to be getting all worked up about it.
We were trying to keep that thread on-topic, because we knew right from the start it had the potential to quickly go off-topic into a direction that is specifically not allowed on this forum, per our forum guidelines. Once it became apparent that a few deletions of discussion of perpetual motion and repeated warnings within the thread were not stopping people from veering off in that direction, the thread was locked.
That's it. Discussion of it is over.
