Fake or real? That is the question.

I remember my teachers always told me that the website that I can trust and are most valuable are the ones that end in org, edu or gov. After looking at the websites I now know that I still have to be extra careful in the sites I use. Some websites will be easy to spot it it is real or fake but then there are others, like the one I looked at in class, that can be very tricky. I think that it is funny that people make fake websites. I would like to know why they do it.
