The video interview with Daisy just highlighted the lack of privacy these kids have. Not that it wasn't cute, but creeps know her full name, may figure out where they live, potentially where they go to school etc as I'm sure she has done insta stories with them in uniform before. They will know her like and dislikes.
Yes, Daisy asked to do the interview but is it really consent. This is the issue family vloggers will have in the future IMO. Even if older Daisy doesn't care, she has been conditioned to consider it normal so it's a fuzzy line.
