That's not the problem at all. My critism was more like you don't actually do anything against a thread being in the wrong section. You only close it, leaving it there. I don't know if it's normal moderation around here, but looking at how a board works, that doesn't resolve anything. If user will use the search function on a specific forum they will miss all the missplaced threads being closed somewhere else, who may happen to contain the solution to their questions/problems. So this moderation is not very useful for future users. And you don't really help the present uses either. First they may be the thread creators and as such, they won't like the closing at all, of course. You will cause them more work than it would be for you to move it to the right section instead of closing the thread. As such, when they realize that, they might start to like you less, to say it nice. Second, if not thread creator, they mostly either do not care of the thread being at the wrong section at all or they do. Latter won't be helped getting a missplaced thread closed in the Game Development Section at all, since there is no hyper activity and as such the closed thread remains visible on the first page of threads for weeks, still being missplaced.
So, since I got your "no clue" that way that you don't actually have a reason for not following my suggestion, I would like you to overthink my reasoning and change your moderation by any chance. Unless, of course, you have some huge points speaking against my reasoning. I would like to hear them, then.
