Ask HN: Do you stalk Facebook profiles?

Similar to: http://bioischanged.com/privacy but for Facebook :)

Slightly tangential, but what's to stop me flipping one bit in a JPEG and uploading it again. JPEGs are renowned for being fault tolerant to even the most aggressive mangling of the file structure, as long as the header is intact it will preserve some integrity

You can favourite your friends on Facebook, and get notifications whenever they post or change their profile picture.

Sorry I missed one thing you can get notification of profile pic update of any one be it your friend or not

Isn't that called the Feed in the world of Facebook ?

No no you got it little different, you can get notification of profile pic of anyone ( you have choose ) be it your friend or not

Then that's called "following" somebody. You can do that without their consent, but of course you only have access to updates that you'd be able to see as a non-friend.

Facebook will shut you down if you become popular.
