Google Chrome 上預防 Clickjacking 的套件...

Gene 寫的「如何在你不知情被自動加入粉絲團的秘技, 以 "粉你的" 作示範」這篇裡面用到的技巧叫做 Clickjacking (點擊劫持)。

Facebook 有給出「What is clickjacking?」的說明,不過相當白話 (而且沒有幫助 Orz)。

技術上的解釋是,其中一種實作是在要點擊的對象上加上一層「透明的」DOM 物件,當 click 時就會點到該物件。目前最常見的是 Facebook 的 Like 按鈕。(i.e. Gene 寫的那篇)

Google Chrome 上可以用「Clickjacking Reveal」這個套件:

This extension tries to warn you if it found clickjacking technique on the page you are viewing.

Tired because of webpage tricks you into clicking social network buttons? This extension will try to detect those hidden bad buys and force them to show themselves.

效果是這樣:(範例出自「胖妞變身大美女 甩肉40斤練出腹肌」這篇)
