Facebook current privacy issue made clear

Facebook privacy

Issue	Brief description	Severity	Why this is severe
Bugs	Some privacy options don’t work as they’re supposed to	High	Just when you are so certain you have setup the proper privacy protection, your profile and activities burst and your private information is exposed.
Version control	When Facebook upgrades functions or migrates data, certain functions are temporarily reverted back to the old version. One that occurred to my account was Live Feed Options.	Low	You thought you have moved on with newer and more interesting things, but suddenly something reverts back to what it was.
Default settings	New information or information in sections that are changed by Facebook are, by default, visible to “Everyone”.e.g. Likes and Interests May 2010	Medium	It takes users a while to figure out how to set privacy for these sections.
Lack of settings	Certain settings are not provided. e.g. Pages I am a fan of	Medium	You can’t put control on the items you want.
Changing settings	When Facebook upgrade certain features, privacy options related to that feature are sometimes lost. e.g. Option to set for newsfeed not to display comment one writes on his/her friend’s content. I used to set it, and couldn’t find it again.	Medium	I am confused.
