So there's this question How to stop Visual Studio (2019) from adding line on the end of file?, which clearly had some problems, but with patience and effort I was able to work through it in the comments with this relatively new SO user and get their question to the state that it could be answered.
And then a moderator closed it with one vote.
There already was one vote to close made before I was able to explain to the OP why we needed additional information from them, so that seemed reasonable. However, whoever used the mod hammer to close it (it's hidden behind the Community account, so I don't know who it is) did so after the OP had edited the question to an acceptable state, so it just seems vindictive.
And now, after doing the work to get them to the point of understanding and adding the necessary information, and then doing the work to be able to answer the question, as I was entering my answer, the question was Closed ("no more answers can be added"). So now, at best, I have to go through the process of hoping that 4 other contributors will notice and vote to reopen.
I can understand why new users are hard to work with sometimes. I really cannot understand why after well over a decade, SO is still doing stuff like this. So why is that?
When it's done by the Community user, it is always the author of the question that clicked the button to confirm the other question resolved their problem
Ah, right. I did not know this, my bad. I would like to delete this question now, but it was fairly answered and they deserve the points. Plus I am probably not the only person to not realize that "closed by Community*" means that it was closed by the OP, so I will leave it for posterity.
