Are these people REALLY that famous? I'm sort of interested in them insofar as I can't believe these people who don't offer ANYTHING have made so much money from essentially doing NOTHING.
they're not "famous" in the way we would define the word - but having a large presence on social media means the girls are definitely recognisable and have a large fan base of other teens - thus it goes without saying that there are likely people who are jealous of them, and/or have creepy/harmful intentions. and i'm not saying anyone would necessarily go out of their way to seek Kaci out, but there are some weird people out there, and sharing her numberplate makes her even more likely to be recognised, which places her at unnecessary risk. it's one thing being recognised in public and being asked to pose for selfies, but it's different if you're driving alone in your car and being followed - sure, it's unlikely to happen, but if i was a parent, i wouldn't take the risk.
even a situation where someone who is jealous of Kaci being able to buy a new car could take advantage of knowing her number plate, to damage her car or whatever, because if they saw it parked somewhere, they'd know it was hers! it just seemed a stupid and unnecessary detail to publicise!
