The Shambles, I don't think anyone doubts that you are the only person this sanction is applied to. It is a situation of your creation.

What we don't know is whether this "rule" would be applied to anyone else should they persitanly have multiple threads on a topic, etc. While I hope it is never put to the test, my own feeling is that you have set a precident and that any other poster constantly behaving in the same way would receive the same treatment.
