Yeah OK but then there are 100s of other general principles you need to know in life. Calling someone stupid every time someone doesn't follow one of the things that's obvious to you is not constructive. We need things like this to go public to avoid them from happening, and shaming victims doesn't help here. The author is already extremely apologetic in this post, and still there are people saying he's stupid for almost falling for it. I am usually quite rational, but I've done some pretty stupid and embarassing things at times where I was not thinking everything through. I imagine most people have. Imagine you go to vacation to Paris, take an evening walk and get mugged. Your attitude is like the local saying "what an idiot for walking around in that neighborhood at night".
