Part II: What happens to your sent messages when the other user deletes their account?

In the first part, we looked at how WhatsApp, Telegram, and Facebook Messenger manage your messages when the other user you were communicating with eventually deletes their account. If you consider platforms like X (formerly Twitter), Instagram, and LinkedIn, these have become essential for communication—whether it’s casual chats, professional networking, or sharing your latest thoughts with the world.

But what happens to the messages you’ve sent when someone decides to delete their account? Do they vanish into the digital void, or do they linger in your inbox as ghostly reminders of past conversations?

To answer these questions, let’s dive into how these platforms handle message retention and deletion, especially when one party decides to leave for good.

X (Formerly Twitter): The Case of Lingering DMs

X is a platform known for its fast-paced public interactions, but its Direct Messages (DMs) offer a private space for users to communicate. When someone deletes their account on X, here’s what happens:

• Those Sent by the Deleted User: If a user deletes their account, any DMs they’ve sent to you will remain visible in your inbox. However, on their side, everything is gone. Their account no longer exists, and they lose access to all their messages.
• Those Sent by You: Similarly, if you’ve sent DMs to someone who later deletes their account, those stay in your inbox but lose their recipient context. The other user is effectively erased from the platform.
• Deactivation vs. Deletion: X offers a 30-day deactivation period before accounts are permanently deleted. During this time, DMs remain accessible to both parties. If the user reactivates their account within this period, it’s as if they never left. However, if they don’t return after 30 days, their account—and all associated data—vanishes for good.

If you’ve had meaningful conversations with someone on X who deletes their account, you’ll still have access to those chats. However, without the recipient’s account active, those messages become one-sided relics of a bygone connection.

Instagram: A clean slate approach

Instagram is all about visual storytelling and private connections through Direct Messages (DMs). But when someone deletes their account on Instagram, the platform takes a more definitive approach:

• Messages Sent by the Deleted User: Once an account is deleted on Instagram, all DMs sent by that user are removed from both their device and yours. It’s a total wipeout—those conversations are gone forever.
• Your Sent Messages: If you’ve sent messages to someone who deletes their account, those messages also disappear from your chat history. Instagram ensures that no trace of the deleted user remains in your inbox.
• Deactivation vs. Deletion: Instagram allows users to temporarily deactivate their accounts instead of deleting them outright. During deactivation:
  • The user’s profile becomes invisible.
  • Their DMs remain accessible to recipients.
  • If they reactivate their account later, everything—including messages—returns as normal.

Instagram prioritizes privacy by ensuring that once an account is deleted, all traces of that user’s activity—including messages—are erased. If you value keeping a record of conversations with others on Instagram, this might be something to keep in mind.

LinkedIn: Professional privacy first

LinkedIn is the go-to platform for professional networking and career growth. Its messaging system plays a critical role in fostering connections and opportunities. But what happens when someone deletes their LinkedIn account?

• Messages Sent by the Deleted User: When a LinkedIn user deletes their account permanently, all messages they’ve sent are removed from both their inbox and yours. This ensures that no professional correspondence tied to that user lingers after they leave.
• Your Sent Messages: Similarly, if you’ve sent messages to someone who deletes their LinkedIn account, those messages will also disappear from your chat history.
• Deactivation vs. Deletion: LinkedIn allows users to deactivate their accounts temporarily:
  • During deactivation, profiles are hidden but past messages remain visible.
  • If the user reactivates their account later, everything is restored.
  • If they choose permanent deletion instead of deactivation, all data is wiped clean.

LinkedIn takes a thorough approach to privacy and professionalism by ensuring that deleted accounts leave no trace behind. This policy aligns with its focus on maintaining a clean and secure professional environment.

Threads: Meta’s Newest Platform

Threads—a text-based social platform launched by Meta—is still evolving in terms of features and policies. However:

• Since Threads is closely integrated with Instagram accounts (you need an Instagram account to use Threads), its policies around deletion are likely similar.
• If someone deletes their Threads profile (or linked Instagram), it’s probable that any direct interactions or messages will also disappear entirely.

As Threads matures as a platform, we can expect more clarity around how it handles message retention and deletion.

Messages Handling Across Platforms

Privacy vs Permanence when messages are deleted

The way platforms handle message retention after an account deletion reveals a lot about how they prioritize privacy versus accessibility:

1. Platforms like Instagram and LinkedIn take a strict privacy-first approach by ensuring that all traces of deleted accounts—including messages—are removed entirely.
2. X strikes a balance by allowing remaining users to retain access to past conversations while erasing the deleted user’s presence.
3. Emerging platforms like Threads are likely leaning toward Instagram-style privacy policies but may evolve as user feedback shapes the app’s future.
