This question already has an answer here:
I recently stumbled across an old account of mine that I've lost access to, and filled out the form to have it merged.
The questions are unanswered, but I'd like to know the answer (and, apparently, so would others). Clearly this is an answerable question... either it's like that by mistake, and should be fixed, or it's like that for a reason, and an explanation can be given. Duplicating those questions doesn't seem like the right approach, I'm sure it would just get closed as another duplicate.
So, what's the proper way to investigate things that have been asked before, but not answered? I'd bump the other question, but I have nothing significant to add to the question, and don't have an answer.
Edit: The answer to the question marked as a duplicate does not apply here, for reasons I've already explained (I have nothing to add to that question; also, it's not mine. Further, the question discussed there apparently had answers, the question discussed here has none).
