Recently Steam frequent theft of accounts, I urge you to be vigilant. Remember the most important rule "Never give your password to others." This phrase must be understood not only in the literal sense. Never ever enter your username and password than the official Steam client and the official site of the Steam Community.

• Steam Support will never communicates with customers through a friend.
  
• Steam Support does not have the right to demand from you your username or password.
  
• Steam Support will never block your account if you do not break the rules.
  
• Never enter your username and password to third-party site and does not transfer them to other people.
  
• Try not to pass on unfamiliar links sent from friends, if you have no antivirus.
