What is if you block someone on discord can they see your messages?

When you block someone on Discord, they can no longer see your messages in servers where you share a mutual server. Specifically:

• Direct Messages (DMs): Blocking prevents them from sending you DMs. You won't see their messages, and they won't see yours.
• Server Text Channels: If you share a server, your messages will be hidden from the blocked person. They won't be able to see anything you post after the block. However, your old messages will still be visible to them unless you manually delete them. Similarly, you won't see their new messages.
• Voice Channels: The blocked person will not be able to hear you in voice channels, and you won't be able to hear them.
• Mutual Servers: If you are in a mutual server with the blocked person, they will not be able to see your messages.

In short, blocking on Discord is designed to prevent the blocked individual from interacting with you and seeing your new content. You can look at these concepts for further information: Direct%20Messages, Server%20Text%20Channels, Voice%20Channels, Mutual%20Servers.
