In general it is a very good question, but IMVHO not one suitable for asking on this site because:
- it is asking for an extended list of techniques/locations
- it will provoke argument when someone disagrees with any particular entry
- many of the techniques require training, knowledge and skill to be able to apply correctly
- personally I would be reluctant to just start publishing a list - it's the holy grail for any martial arts wannabe
The example you linked to was a bad question no matter how you judge it. It was vague and open ended, had zero research behind it, and I would suggest the OP has little training (if any).
Note that I'm not against questions asking about knockouts, I just don't think this site is always the right place for it. Even simple questions like:
There's a great knockout spot on the side of the jaw, how do I attack it?
is verging on not suitable for here. It is very specific with its location, but there can be a hundred different established ways to attack that spot depending on which art you want to talk about - which is where it starts to become unsuitable for this site because it requires an extremely extended discussion or answer(s).
So how can we cover this sort of topic?
Some of this stuff can be covered in the tag wikis. Some of it can be in a question if it is specific enough. Questions that have several possible answers are still fine even though only one can be marked. But what we must avoid is:
- lots of discussion instead of answers
- questions that ask for lengthy and non-definitive lists
- questions that produce one line answers (or lists of one liners) - we want explanations and detail
- answers that are highly debatable and likely divide the community along cultural or martial art lines
But wait, there's more...
So that's my response, both personally and as a moderator, based on my many years experience using the Stack Exchange network. But frequently boundaries are vague and none of this is set in stone - the site belongs to the community and it is up to the community to set the direction. What are your thoughts on this? Does someone think they know a way that this can work and they want to take a crack at it?
