Just got an evil idea.. You can target on fb and Google by email lists. You create some stupid web app with questions and promise something in return, a prize, or make it worthwhile to play and target them with all the security questions email accounts or whatever might ask. Could be that this is being done for phising already if the victims are being targeted specifically and don't have 2fa.
You are late to the party. I remember receiving this kind of questions in 2006 when hotmail and msn messenger were still popular. I think it was part of a game to measure how worldly you were.
I've been seeing a lot more articles blocked by "surveys" these days. Normally there's a skip option. The mirror group of sites are especially bad for this.
