See https://askubuntu.com/questions/1124917/off-wi-fi-led-in-ubuntu for an example:

While it's ideally better to ask posters if, in this case, lubuntu and syslinux are indeed relevant to the question, suppose posters doesn't respond or, even worse, come back?

If there's no clarity from posters, and other Ask Ubuntu users don't take action (and I too forget to come back to this question later), these tags will result in "false positives" for people who are monitoring, for example, the lubuntu tag.

I'm inclined to remove such tags when I first encounter them. If posters feels they're germane, they can simply add them back.

What is the correct course of action here?
