While some may consider it silly to go into such depth about such a seemingly simple anonymous silencing of a user on "just" an online forum, the discussion does serve a very important purpose. These type of policies should not be put into place without careful consideration.

Your position is very admirable. Thank you for articulating it so well. People are listening :).
