When you mute someone's status on WhatsApp, you will no longer receive notifications for their status updates, and their statuses will be moved to the bottom of your status list under a "Muted Updates" section. However, you can still view their muted status updates manually if you choose to. Muting someone's status does not affect their ability to see your status, nor does it notify the person that you have muted them. In summary:

• No notifications for their new status updates.
• Their status updates appear in a muted section after the main status list.
• You can still view their statuses if you scroll down.
• The muted person can still see your status updates.
• Muting does not block or restrict messaging or calls.

Muting someone on WhatsApp is mainly a way to avoid status update notifications without blocking or hiding any information from the other person.
