Looking for a content-locker until page is facebook-liked

[xexmodder]

I'm looking for a wordpress plugin that hides content in a post until someone likes the page, like this: http://codecanyon.net/item/wordpress-like-locker-like-to-read-plugin/166051

But I'd like a FREE plugin. I tried out like-gate but it doesn't work.. Any suggestions for a free plugin that does the same thing as this one? Thanks..

You can use sites such as scriptmafia to download this exact plugin for free for testing/educational purposes.

Usually stuff from scriptmafia is backdoored.
