How can I disable the Facebook apps that appear on my wall all in one go?I can disable applications individually on my wall (the applications that my friends posted), but how can I disable them all? 
Disable all Facebook apps posted on my wall

There's no way to disable them all at once. You can, however, block all invites coming from a person, so if there's one person sending all the app invites, you can add the person to the blocked app invites list available in Privacy Settings.
