The logic is that you need to think twice about posting when you see notice like this… Heated topic usually get closer to chat-like experience where few users fight. In past we only could close the discussion (and open it later when it calms down). Now we can also slow it down…
Being able to rate limit a conversation so that people who’ve already posted can’t be tempted to jump in and defend themselves, constantly clarify their remarks, demand explanations,
This would put everyone on notice that the topic is being watched carefully and they need to choose their words more carefully here, as opposed to the more free areas of the forum.
However we need to experiment with finding the right amount of required time between posts…
