This scam first traps you through comments or status such here is your friend , let's call it X .

“I just enabled the dislike button and you can also enable it by clicking on enable option” (1st scam)
OR
“I just have enabled dislike button and it is really cool . You can also enable it by visiting and downloading script from WWW.XYZ.COM. Already 46507 users have activated this” (2nd scam)

Basic Scheme of this scam:-

In the 1st scam your friend X is asked to click on the enable button . When your friend X clicks and downloads the script , all of his friends get a wall post by X , asking to enable the dislike button in the same wording.
In the 2nd scam your friend X is asked to visit a certain site to download a script . Now if X does the same mistake again of downloading that script his all friends would get a wall post , asking to enable dislike button including you . And if any of yours friend does the same mistake as X did then this script would also flood the wall of his/her friends . That's how this script spreads on the Facebook.

What is Reality:-
