Mob lynching-Another problem of India

Now a days mob lynching increases just because of fake newz. When people read a fake newz like child kidnapper, rapist etc forward it without analysing or finding out the truth of this message.In last 2-3 month many innocent people were died just because of fake newz.How we will stop to spread fake newz. How we konw that this is a fake newz.And one good newz is that whatsapp launch a new feature that any fake newz if share by pepole is come with red line. Which help you to know that is a fake newz.If other social media introduced any feature that recognise fake newz, i think it reduces 95% of mob lynching. .
