I’m using Facebook recommendations on my blog( http://techdreams.org ) to display most liked/shared content. Today I noticed that top most link on my sites recommendations is from an unknown site with url “http://79h.taiwan-talk.org/like.php?pid=822“.
Can someone please help me to get rid of this spam link?

This was an open bug in Facebook’s bug tracker – details here: https://developers.facebook.com/bugs/243312152381418
It was marked as fixed on Friday so it should be resolved now – if you’re still having the issue you should follow up on that bug report or file a new one
