Facebook does not offer a "Dislike" button, and no matter how many "Dislike button" Facebook page petitions you "Like," how many chickens you sacrifice and how many birthday candles you waste, there likely will never be one.
Think about it.
"Dislike" just doesn't fit with the Facebook credo, which is about social connections and promoting things. It doesn't work like YouTube, where you're rating one thing — videos — with an thumbs-up or down. Facebook wants everyone — including and/or especially product pages — to have a thumbs up experience. And let's face it: You people can't be trusted. Give the unwashed Internet masses the ability to "Dislike" something, and most assuredly things will get ugly fast.
You know the old saying: Those who don't remember Facebook spam scams are destined to annoy their friends.
It's a trap!
Facebook says it's working with major Web browsers to fix the security holes that allow malicious apps to slip into the social network. Last week, Facebook rolled out security updates to help clean up the site. But common sense can go a long way towards not annoying your friends, too.
Consider the case of the "Dislike" button which you're asked to click to install.
