I’ve not met a single person who loves to be on the receiving end of Facebook App notifications. Be it Candy Crush Saga, Bubble Witch, Farmville, Mafia Wars or Bejeweled Blitz.
I’m also surprised by the number of people who have no idea how to stop this menace. Here is a quick 2-step process on how to block this spam:
Step 1
Go here: https://www.facebook.com/settings?tab=blocking
Step 2
Scroll Down to Block Apps and enter the name of the app. That’s it, done!
BONUS
A friend sending you invites for too many games or apps? Use the Block App Invites From section on the same page
Getting too many event invites from a certain friend. Use Block Event Invites. BOOM!
Awesome!
