Re: Found a vulnerability
It can only collect what you willfully place on it.

I've still no idea why so many people (my wife included) spend so much time/effort on it
So your last statement is a confirmation of the first in that you just don't get it? Fair enough. It's like this: FB promises hours of free mindless entertainment and encourages users to give up everything about themselves under the guise of allowing them to keep up with their friends, to confirm their pre-existing biases and to look at memes. They then take all the information they harvest, with or without their users' knowledge, and sell it over and over. People are good with this because mindless is mindless, after all. It's easy to take advantage of folks if they think they are getting something for free. If there is nothing physical for them to see being taken from them, they will never notice the loss.
