How do you know if someone blocked you on Snapchat?

There are a few signs that may indicate that someone has blocked you on Snapchat:

1. You can no longer view their Snapchat score or see their Snaps in your feed.
2. You are unable to send them Snaps or messages.
3. Their username or name is no longer visible in your friend list.
4. You are unable to find their username or name when searching for it on Snapchat.

Keep in mind that these signs do not necessarily mean that you have been blocked. There could be other reasons why you are unable to view someone's Snapchat score or send them Snaps, such as if they have deleted their account or if they have not accepted your friend request.

If you are unsure whether or not someone has blocked you on Snapchat, you can try searching for their username or name on the app. If you are unable to find them, it is possible that they have blocked you. However, the only way to know for sure is to ask them directly or try creating a new account and adding them as a friend.
