Beware of all these
I don't think that listing 4 possible email templates will help protect people.

I would say not only beware scam emails but also fake sites (phishing).
In general everyone involved in Bitcoin should study computer security a bit. Read basic articles, then more advanced ones, anything you will do will help here, you set the limit how much u want to learn.
