To me, without doubt it is the “My Questions” app. So many times I have been tricked into checking out questions that friends have asked, only to find that they never asked the question and are confused why it was asked on their behalf. This just happened to me. I logged into Facebook and found that a friend had answered my question. Nice, except that I never asked a question.
While Facebook is becoming more and more a part of my daily life, I am really wary of spammy apps like My Questions.
What is the app that you find most spammy on Facebook?
