Read teh Rules

[Cell]

The rules also state that Mods are always right

If the mod says breaking the block above the chest is griefing, then its griefing. Then is when you appeal on the forums. You don't appeal if you know you did something wrong, but if you did something that isn't against the rules and was interpreted to be against them, then you appeal.

And also, Moderators are very lenient about the rules for a good reason.
If mods where to ban everyone the first, time they broke the rules, or for say "Flaming" once in global, then there would be no people yet.
Think about it from this view as-well.
In my school Teachers under order of the Principal, are to remove cell phones as soon as they are seen, and then contact the parents.
Do they "Always" remove the phone, no, half the time they usually just say put it away, or next time they will.

I do see what you are saying though, as in what rules are what, and such. If you feel that a Mod is not doing this and that right, talk to them about it, etc. Maybe the moderator thought you where going to break the block and replace it with something different. (Ex. Smooth stone, then replacing with Dirt). Its better to do that rather than making a thread about it saying that they should read the rules, and etc. Its much more offensive to do it like this, than to stay under the radar and avoid any flaming issues etc.

Apologies for my lengthy reply.
