I believe this is implied, but to those who aren't seeing it, it may put them at ease: I'm sure any and all forum posts complaining about punishment will simply be deleted and the offender punished, perhaps more harshly than before.
Like all things, it depends on how and where you do it.
Derailing a topic with whining about some mod action? Definitely worthy a deleted post and another warning.
Opening a new topic, in the appropriate sub-forum, with a calm and reasonable argument? That's the way to do it.
