Moderation log
In the spirit of full transparency, I believe there should be a "Moderation log". This log should be visible at all times and accessible to everyone. This log does not need to be extensive, just something like:
[name_of_mod] removed/silenced/hid post [post_number] on DD/MM/YYYY.
This should be done for both posts and comments as well as actions on users (banning users for example).
