I have been getting similar Whatsapp messages from many relatives and friends sharing about free vouchers, free first class tickets and other click baiting promotions. And these messages show an authentic URL but the real link behind is the same (leads to some http://xn… link)! If you get such messages PLEASE STOP sharing them! Here are some of those I got so far.
Don’t share them please!
Nothing in this world is free, especially if they sound too good to be true! Stop blindly sharing and be smart enough to know what’s real and spam!
