This rule is very important. Like many of the other rules, it is open to interpretation, but it is a line in the sand that defines allowable behaviour and disallowable behaviour.

This rule will have an effect on the behaviour of the 'good players', and make the 'bad players' a lot easier to spot. Moderation needs this. I see this as stopping a race-to-the-bottom on value extraction from HN as a platform.
