I have seen some users using drupal.org for questions that are not about drupal.org; probably they pick up that tag because it contains the word "drupal." This reminds me of when on drupal.org users select "drupal.org module" as issue component, when that component is referring to the Drupal.org customizations module.
Is it possible to use a different name for the tag, to avoid it gets misused?
I removed the tag from other 7 questions. The questions from which I removed the tag where questions about modules, or code to write for modules. The tag is not going to be picked up because it's not clear what its purpose is, as the tag has an excerpt.
I think that the tag is being picked up because the users start writing "drupal," they get a suggestion for that tag, see it doesn't contains specific words (which would happen with drupal-commerce), and decide the tag is right because Drupal.org is the official Drupal site, where the Drupal development is planned.
It would probably help if "drupal" would not be the first part of the tag, and if the tag would contain another word, such as in community-drupal-org.
