Answer: No, Snapchat does not alert the concerned individual in case you leave their friend request or reject the request.
Explanation
Snapchat should aim to be friendly and comfortable to the users, in particular in the area of adding friends and removing them. Once another person makes a friend request to you, their names will be visible in your Added Me list. However, in the case, when you decide to scroll or just ignore them, they will not get any notice or signal that you did it.
In case you reject the request, both the request is no longer on your list, but the person who sent the request still would not be informed whether you declined it or you have just not responded to it yet. Snapchat lacks any option such as ignored or declined, which means that the sender does not know anything unless you go out of your way and add him/her back.
But, when they attempt to send a message to you and you do not block them back, you might get messages on your account that are labeled as pending, and this is a hint. Nevertheless, this does not reaffirm the fact that you are deliberately not listening to the request.
The company adopts this approach so that you can prevent awkward situations, in particular, when you do not want a person to realize that you had not decided to connect with him or her.
FAQs:
Q1. Can someone tell if I viewed their friend request and didn’t add them?
A: No, the Snapchat does not tell when you received the request and if you did not react to it. They will simply keep posting your name on their Recent Added.
Q2. What does it mean if a friend request disappears?
A: This may occur when they cancel the request, you rejected it or they deleted their account. Snapchat does not provide precise inferences.
Q3. Will someone know if I block them instead of ignoring?
A: No, blocking also happens silently. They will not locate your profile and reach out to you, yet will not be informed that they are blocked.
Q4. Can I remove someone after adding them on Snapchat?
A: Yes, you can block or delete them at any time at your friend list. They will not receive any direct notifications.
Q5. How do I limit who can add me on Snapchat?
A: Go to Settings > Privacy Controls > Contact Me and turn it into My Friends to prevent random ads
