The limit would be applicable only to the Indian users. "The limit has started to appear this week for people in India who are on the current version of WhatsApp. This week, WhatsApp is publishing a new video that explains the importance of the 'forward' label and calls users to 'double check' the facts when you're not sure who created the original message," the company said.
While this move would not stop mass forwards, it certainly makes it difficult for the user. If you try and forward a message to the 6th person at one go, the app would tell you that you can forward only to five people. However a user could go back to the message and forward it again to another five contacts or groups
