Remove the "last seen" info

[Cardioguy]

Would anyone know how to remove the "last seen" info that is shown when someone looks at your user info?
I notice there are members that have that info absent so I am assuming it is possible but cannot figure it out.
Thanks in advance

It looks like you did it without knowing it. Because I can't see your "last seen" info. I assume it's the "Show your online status" option in privacy settings.

It may seem like it didn't work because I believe you can still see that info about yourself, but the privacy settings just stop others from seeing it.
