I answered a question the other day, as did someone else (same question, I mean!). The OP has in his about me "Detail-oriented. I upvote detailed answers to my questions." I wrote a detailed response*, but he never responded to it (and often didn't respond to other people). So I wrote a comment saying "Does my answer sort your confusion? :)" to which he replied "nope it's not detailed". Firstly, as you can check yourself, (as far as I am aware) it covers all the required details. Secondly, (at least in my opinion) detailed answers are not necessarily the way forward: whenever I write a question, unless I'm extremely stuck, I shall always end it with something like "please leave a hint, not a full solution so that I can work it out myself" (obviously more politely than that!).
*I originally had my answer giving the method, then saying something like "I leave the details to you" (again, more politely!), but then I realised that the details were just one line and someone else had written them anyway, so I added them in.
The OP has now edited the question to include his method, and has not responded to any of the people.
Looking at the users other questions, I can see that he doesn't very often accept answers. A lot of his questions (not all, by any means) are related similarly. The question is now on hold because he has put a solution (again, ironically, without full details) in his question, so it's not clear what he's asking.
Is there anything that should be done about things like this? I'm not talking about just this one case, but in general. I have seen this sort of thing before where other users have spent considerable time helping someone who then ignores the helper, or even just closes the question after getting their answer (I know there's a meta question on the latter!).
I've seen before a user 'benched' - I can't remember exactly what for. Could potentially add an option under 'flag'? What do people think? :)
