Way back in 2005, a kid named Chris Putnam wrote a computer virus that rapidly spread across Facebook.
The bug's effect was to make Facebook users' profiles look like MySpace profiles. Unfortunately, the worm also deleted some users's contact details.

Facebook soon found out that putnam was behind all this, but instead of having Putnam arrested, Facebook hired him!!

PS- If you write :putnam: while chat you can see his emoticon!!
