I recently had a comment taken down by one of the mods without any explanation why. It was biting sarcasm mocking paranoid right-wing conspiracy theorists which, as far as I can see, was not in violation of any community standards. The mods ought to make it a practice when challenging a comment to state the reason why, identifying the particular community standard which it offends. Anything less makes it appear that the mod(s) is/are arbitrarily censoring content unless the violation is flagrantly obvious.
