I've closed like that. One asker complained that his question about base64 encoding in one language was not like the duplicate I identified because the language was another one. "Vaguely related", he thought, but he asked precisely because he didn't know.

surely the answer is to tell him his language is wrong, if enough people have that problem that is the answer.

Show, don't tell.

Try answering some of the recently closed questions on SO, see how much time you're willing to spend on them. (As a practical matter: You can do it with the comment function, or search for questions that have two votes to close already.)

Any mode of answering is okay. If you find out that it's not deathly tiring, let us know how.

This seems to somehow work fine on discord, where people ask the dumbest of questions on project discords yet get prompt responses even if it's just a link to a faq or wiki. I don't know how this happens, maybe something about the chat format or SO not retaining responders as well as discords do, but you really can see this it on discord servers for projects.

Maybe it works at a certain (small) scale. And if you don't care about being able to find the question again in 1 week / 6 months / 10 years.
