Sometimes people open issues without proper information. It cant be replicated and nobody else is jumping in that it affects them. You may suspect its something else, maybe with their environment, but if they don't engage what else can you do? Tell them you are closing it and specify what kind of info you need if they ever get around to providing it and it can be reopened.

"Unable to reproduce" is a fair enough explicit close reason. This is more about those "stale" bots that exist that just kinda close the issues because there hasn't been any response for X days. The annoyance with the practice usually stems from the fact that many of the victims of this comes from a lack of maintainer response.

This sort of bot punishes users for making even valid reports that aren't fixed immediately or missed by the maintainers for whatever reason including transitory ones, etc.

Constantly bumping threads/issues/whatever is generally considered rude, so this is why issue reporters generally don't do it, plus generally the reporter isn't solely focused on that particular issue

And sometimes the maintainer simply doesn't respond to a perfectly acceptable issue due to either the maintainer abandoning the project, not enough maintainers or simple neglect.
