Adding to Whatsapp is a new feature to catch a kind of spam spam called Shady Link.
This feature will identify harmful links within the message, and WhatsApp will warn you that the user will not click on that link. According to Mashable, one representative of the company.
Adding this feature is mainly due to a special type of spam created by spammers and fishers, whitesapay. Such spam is spread through a link, where there are strange signals, and they seem like a common alphabet. As if looking at the link below, it may seem like it is a very common link to WhatsApp. But if you notice very well, there is a dot sign below its W-mark.
