A lot of people put a lot of emotional stock into Facebook. That sounds crazy, but let me explain.
I'm going into my junior year of college. About a month and a half ago, a well-liked girl from my high school class and her entire family died in a car crash in California. My news feed was suddenly flooded with posts to her wall of people trying to find some sort of closure. Personally, I didn't know her too well, but we had a lot of mutual friends. Many of my friends still post on her wall, because it's their way of dealing with the tragedy.
If Facebook just closed the account, many of my friends would just be bottling up their emotions. I'm sure it's a weird thing to think about if you're not used to thinking about Facebook, but it does provide some sort of healing in a situation like that. If nothing else, I want Facebook to keep the pages of the dead open to help in a case like this.
(For what it's worth, I never found their banner ads to be terribly intrusive, so I never AdBlocked them. That's changing today.)
A quick glimpse at Wikipedia shows that Britney's first album was released in 1999. She was born in 1981. This means that at most one album was released when she was in the legal pedophilia age limit. Overly sexualized and creepy I'll agree with, but Britney Spears does not embody pedophilia.
