I'd say "news" and popular shows give most for such impression. Good yellow tint in them helps to attract larger auditory, but many people think the life is "like that" indeed. It's like to watch "criminal news" everyday and cause of this to scare walking on streets. Or to read health magazines and such to get hypochondria.
The life of most modern people is rather boring so their excessive impression helps to add colors in it. I suspect much of neuroses and anxiety disorders would disappear in case of really harder life. Our brain needs more stimulation and plays with us.
You may remove a video after typing. I doubt someone will repost it publicly, except rare cases.
Also there is nothing seriously bad what you need to say in the typing. It's general info, what people see or feel in you anyway.
I understand that you being Se is more suspicious.
