I noticed today that we have an information tag. It seems like it started out benignly, and it has been used for questions about getting system info from the phone or where your personal information is stored. However, I noticed it because this question was tagged with information, seemingly because they were looking for information about a specific topic.
I personally think it's kind of a vague tag, and would be prone to further misuse (like above). My initial thought was to possibly create instead a system-info tag and a personal-info tag (or similar) since I think they would be much less likely to be used in unintended ways. We already have a user-information tag, in fact.
