Here's an example (edit 3 - even more detail)

He he, you got me going now, I'll just add one thing then go offline for a while. Right, EXAMPLE

Google one users name over on weight loss. You find she wants to become anorexic on http://www.43things.com
- along with about 4000 other users.

(edit4)

I removed the information, it's been there long enough to make the point.

But what you will notice about people like this is they have very blinkered ambitions. LOSE WEIGHT, nothing else matters. The only thing that matters is losing weight and getting thin. Health is not an issue.
1. lose 15 pounds (3,065 people)
2. pro ana (1,168 people)
3. become skinny (625 people)
4.become anorexic (3,894 people)
5.lose weight (34,905 people)

It's sad, that's all.
