What is how do you know if someone deleted their snapchat?

As an AI language model, I do not have personal experiences or ways to access Snapchat accounts. However, here are some ways to tell if someone deleted their Snapchat account:

1. Search their username - If the username does not appear in your search results, it could mean they have either deleted or deactivated their account.

2. Check if you have any pending messages - If someone deletes their account, all their messages will disappear, and any pending messages they sent you will not get delivered.

3. Check if you have any past snaps - If you cannot find any past snaps from the user, it may be another sign that they have deleted their account.

4. Ask the person - If you cannot find them on the app, you can try reaching out to them on another social media platform or text to ask if they deleted their account.
