Some questions are blatantly off-topic, to the point that no explanation is needed beyond stating this fact. I'm not using a real example, but the situation is not hypothetical.
One of my front teeth is loose, is there anything I can do to fix it in its place?
This looks off-topic to me, but what is the reason?
- a question about creating/developing a web application? No, it's not that.
- Application/website recommendation? No.
- applications that are no longer available? No.
- belongs on another site? Not on any we can migrate to, if any at all.
So, one has to write a custom close reason, explaining that teeth are not web applications. This is particularly annoying because it feels like feeding a troll.
On SE sites, the off-topic dialog comes with a pre-filled option:
Not about {site subject}, within the scope defined in the Help Center.
E.g., Mathematics still has it:
I propose adding this reason back to the dialog, so that blatantly off-topic posts can be disposed of as quietly as possible.
