This is called Phishing... nothing new. This is why you never sign into a website through your email... even if it looks legit. If they tell you your account is limited, go to the official site, and make sure you have httpS for a server layer. This means you are on a secure site. You can also look to see the padlock on the bottom right hand side of Internet Explorer if that's what you use. Sign in there and only there... unless you wanna get scammed.
