[Edit, since you guys keep making accusations/poitns/having a discussion but don’t allow discussion back]: There is no sub forum for matchmaking topics. There is no sub forum for “Things equally relevant to AB, RB, and SB” such as various topics about uptiers common to all three (other than General Discussion). So no, the issue is not that people do “not care” nor ignorance nor laziness, by not managing to find a subforum that does not exist in the first place.
Also yes, I did actually search for half an hour for a relevant thread, too. That was not hyperbole. I never found a pre-existing thread for this example. I asked 2 different moderators for one, as well, and they couldn’t find one either, in PMs.
So at the end of the day, the guy’s thread was locked because he didn’t put it in a non-existent better fitting sub forum, and he didn’t continue a non-existent prior thread. “You lazy player, you didn’t discuss this in the right place!” “Okay, where is the right place?” “I dunno”
In order for a moderator to lock a thread for “Not continuing the existing thread on this topic”, they logically must already know of and be thinking of a specific existing thread on the topic. Otherwise of course it wouldn’t make any sense to say to “use the existing thread” if one didn’t even exist and if you don’t know if one exists. Those would become impossible instructions.
So since you already are aware of the thread you’re thinking of, why not just copy/paste the link to it in 2 seconds, while locking the other thread? It doesn’t take you any extra work, because you already must know about it, there wouldn’t be any time spent searching.
But it does save the users of the forum a huge amount of work hunting around for the mysterious “other thread” for half an hour to post there, when you already knew which one it was all along.
This would be a lot more helpful to discussion at almost no cost.
(This was inspired by https://forum.warthunder.com/t/why-are-moderators-closing-so-many-discussions-down-without-warning/112209/12 but it’s not about that one thing, and also you locked it so I couldn’t write it there. And this is not a question, it’s a suggestion of policy of general interest.)
