Bernie,
In American baseball, it's three strikes and you're out. You were given more than three strikes. And in 'Doctor No', Bond says "You've had your five".
Your semi-semantic argument holds water like a sieve. While not exact synonyms, in dictionaries the entries for 'cost' and 'price' each use the other word multiple times to define each other. Ergo if 'price' is outlawed, so is 'cost'. Note that prices/costs not relating to guitars were left intact.
Also, I think you are wrong with your blanket slam... Name names if you got 'em. Then call 'em what you like. Personally, I would rather define the 'delete and lock' actions as more properly 'draconian'.
All of that being said, I was actually shocked by what one moderator wrote (and has since been deleted). But only by the act of posting, not necessarily the content (which shouldn't have been posted since it broke the basic rules itself).

edit> BTW, 'draconian' does not mean 'unjustified'.
