The question, uhh... in question:
You can follow along by looking at its timeline. Some parts may only be viewable by high-rep users, I'm not sure.
So, getting on with it. The question was originally asked as a one-liner, and ended up accumulating 4 downvotes by the end of the day it was asked. I added my usual "What research have you done? Bio.SE works this way..." comment, but didn't downvote or cast a close vote because it was asked by an established user, and there was a decent chance they'd come back and edit it into shape. Others didn't feel that way, apparently, and it was closed by two regular users and a mod-hammer. OK, whatever, happens all the time.
However, in this case the asker came back and actually put a decent amount of previous research and critical thinking into the question. Their edit put the question into the Reopen queue, where it was voted to stay closed, one of the votes coming from the same mod who hammered it closed the first time, and the other by a user who had voted to close it in the first place. That vote from the mod seemed to hammer it again.
I revisited the question at some point after this, saw the revision, thought it added a lot of value, and nominated it for reopening, pushing it back into the Reopen queue. The same two people reviewed it and voted to remain closed again, with a mod hammer ending the discussion yet again.
A few questions and a short rant. Why was this post hammered three times by the same mod, even after substantial improvement? More broadly, why did only four people in total interact with it (including me), and why weren't any comments left besides mine, especially when it traveled the review queue twice and was hammered three times, by the same mod? What is so wrong with the edited post?
One takeaway from this is that we need many more people to get involved in close/reopen voting, and the review queues in general. That's a common plea around here, unfortunately, and I haven't heard (nor thought of myself) any good ways of doing that.
The second takeaway is that we need to have a full, serious discussion on the use of mod hammers in closing. Since I want discussion here to focus on this question and this particular set of circumstances, I will ask a second Meta question specifically about that, referencing this one.
