Web Forum posts with poor answers which get locked out

A lot of time when I google or search for topics, I find a post from 2024 or something not too far away… and it was locked out 30 days after it was posted. Why?

Yet some of these posts have an answer that has misinformation, or is written by someone who doesn’t even know about the topic as is just taking wild uneducated guesses that are wrong. And the post will have thousands of views because it comes up first or second in the google search. All these people are being mislead by wrong answers some of the time, and there’s no way to help them. You can’t even mark a thumbs down on the answer.

Can we get a way to downvote “answers?” or be able to reply to older posts? Why are some locked out and some aren’t? Is it because it has an “answer” (which is wrong) flagged?

EDIT:
Also, it would be cool for viewers to vote for an answer, even if there is none declared by the OP. I’m assuming this is why some old posts can still be replied to. So basically.. you can help people only if the OP either couldn’t get an answer, or they were just too lazy to flag a proper one.

Has been discussed a few times. Posts automatically lock after X time, I think even if unanswered. After some time both answer and question are outdated, replies become irrelevant for new engine versions sometimes. Or the person who put the question online has moved on long ago. It’s just an archive.

A downvote would be lacking context. For example, a solution might be correct for UE5.0 but the opposite for UE5.5. A downvote just lacks that context. It’s not enough. It would make a mess reopening posts from 2015 with various solutions or fixes all over the replies.

Eventually… Some sort of compact knowledgebase should be built from filtered forum solutions (to quickly get from question to correct answer), but that knowledgebase must also be correct for various possible situations (UE version, people their OS, hardware) where variations pop up to the original answer.
