Facebook scams trigger curiosity
Some of these things sometimes may feel they are obvious, especially if you are involved in technology. Yet, at the time of being on Facebook taking a break from whatever you are working on, which is what I do, you simply forget about your inner security alert. Well, unless you see on FB something that it's particularly annoying and, therefore, avoid it, as I mentioned before commenting on your other post.
These scams make you also think of human curiosity. Are humans so curious that they will always fall into these traps?
It's great you bring these reminders to our attention. :)
