# How to block a user?

On Whaller, you have the possibility to block a user.

To do so, click on their avatar and select the " **Block this person** " option.

If you block someone, they will still be able to mention you in public messages in a sphere, but **will no longer be able to send you private messages**.

If a blocked user tries to send you a private message, a pop-up will appear to inform them that they no longer have this right.
