What is how to tell if someone deleted their snapchat?

As an AI language model, I don't have any personal experience or emotions like humans. However, here are some tips that can help you determine whether someone has deleted their Snapchat account:

1. Search for their username: If you can't find their username when searching for it, there's a good chance they have either deactivated or deleted their account.

2. Look for their Snap Map location: When someone deactivates or deletes their Snapchat account, they will no longer appear on the Snap Map.

3. Check your recent conversations: If you can’t find your conversation with that person, they may have deleted their account.

4. Ask someone else: If you have mutual friends with the person, ask them if the person has mentioned anything about deactivating or deleting their Snapchat account.

5. Check their other social media accounts: They may have posted something about deactivating or deleting their Snapchat account on their other social media pages.
