(Link per word) There are many questions on gaming.SE where someone just didn't reduce the command's complexity to see what's wrong with it, but instead dumped it into this site, hoping that someone else would do the work for them.
Would it be a good idea to make a "my long Minecraft command doesn't work" FAQ and mark all of these questions as duplicates of it?
The FAQ would give tips and examples on how to reduce the complexity of commands to test them properly and how to then add more complexity back in once it's working, it would link to tools like tellraw generators, it would say why these questions are not wanted here (only useful for one user, not enough research) and so on. Basically it would tell users how to debug and fix errors in their commands.
Just closing these questions without an answer wouldn't be the right action, because they are technically on-topic, just very low quality and not the main focus of this site. Also this Q&A shows that there won't be a "do research" close reason.
But the minecraft tag is the biggest tag on this site, it has a significant portion of questions that also have the minecraft-commands tag and that tag is about 70% filled with questions like these. So it's a noticeable portion of this site that has pretty low quality and could all get caught with this FAQ. It would not mean "f*** you, do research", but instead show actual help for this use case.
There's already something similar to this, but it's limited to unbalanced brackets: How can I fix "unbalanced brackets" in my data tag?
This is not asking for other people creating this FAQ, but only about if there should be one and questions should be marked as duplicate of it. I would start creating it myself.
