I agree with the article's stance on how Facebook enables stalkers to stalk their victims, and the very nature of Facebook makes it easy for them to do that.
If you are at risk of such things, please do not have a Facebook account. With the example of being homosexual in a country where the punishment is death, foreign governments may be able to use Facebook to find you due to any number of security issues that have existed, exist currently, and will exist in the future, so please, just stay off Facebook altogether.
