There are some times where posting things that you know will be negatively received is worth doing anyway. But it doesn't work well if you try it too frequently. You end up with a reputation as a crockpot

You end up with a reputation as a poor communicator. Unpopular but non-obviously stupid ideas that a person (or paperclip maximizer, etc.) tries to articulate are not punished, like here. That came to mind since I participated in the conversation but there are many other examples on LW.
