Ah. That&#x27;s good.<p>I guess that&#x27;s why it has taken a couple of hours for my comments to heavily downvoted (comments that were initially quite heavily upvoted) in my previous attempts at smashing obvious astroturfs - their @all-employees mail needs to get to the employees who happen to have that amount of HN karma.<p>I do realize that going further than this in terms of defenses would be quite a complicated thing.
