How To Block And Unblock Gtalk Contacts
If you are using the native Google Talk app, blocking a person from messaging or seeing you when you are signed in should be fairly easy and straightforward.
However, if you are connecting to your Gtalk via 3rd party apps, e.g, Mac’s Messages, it can be a little challenging as the Blocking option is nowhere to be found.
