Well the above scam is fairly obvious to me for a few reasons. 1. The paypal email address looks funny, 2. The grammar is bad. 3. Paypal never usually does this.
I can see how this would trick people and I once was also almost scammed to give out all my details. I was quite tired and not thinking straight and got a Paypal scam email around the exact same time as I was doing other Paypal stuff so it seemed legit...
Best tip I can give is - NEVER click email hotlinks for Paypal or Banking, always type the real URL into your address bar. Banks and Paypal will never hotlink you to their sites.
