Yes of course they do lack facts. Heck I think mostly they are just figment of someone's imagination. Though at times they sound partially or even entirely true but only based on persistent rumors we've heard. And also yes that stars or their PR probably do sometimes contribute, or so I've learned from IF 😆.
Still, they are kind of fun to guess and try and solve. As long as they are taken as fun and not gospel no harm no foul.
