You know what is so frustrating about scams like these? Even people who are well aware of how these scams operate can easily slip up and enter their login info on a bogus site. Most people who are on the internet alot are very familiar with their browser and do things like clicking links, typing in searches, etc. incredibly fast. It becomes second nature. This sort of thing can happen to anyone.

I always bookmark all of my sites and navigate to them that way. Depending on your habits it is super easy to forget to do this but it will save you from getting burned.
