I was close friends with an "internet celebrity" ca. 06-07, when she became huge on YouTube. She did get millions of views (I believe; she was on of the earliest to monetise YouTube), ended up pulling everything off after being hacked and abused at her home address.

I haven't spoken to her in years but I remember the affect the depraved stuff aome people do - call pizza for delivery, leave things in mailboxes, hack the computer and steal private files, stalking.... It's just crazy.
