Why do people post these silly little "challenges" on Facebook such as, "Name a fish that does not have the letter 'A' in it. Bet you can't"? I assume that when people post an answer they are giving all their Facebook data to the OP? Is that how it works? The "challenges' are so puerile and stupid that people can't possibly post them for any other reason but to harvest users data. At least, that is my assumption. Any thoughts?
