I received an email saying my Paypal account has been limited due to my recent activity has violated some of the agreements with Paypal. I was told to click a link and follows some steps in resolving the issue.
I was about to click the link when I re-read the email, and immediately there were signs of a possible scam such as broken English, the email did not originate from Paypal site even saying "Please contact us, maybe we need to confirm your data."
Be careful of such phishing scams. Do check if the email is from Paypal before clicking on the link in the email.
