We are constantly receiving several messages in which people are asking about an Invisible Gtalk detector. Since Google Mail is at least as popular as Yahoo Mail it is quite obvious that Gtalk is used as frequently as Yahoo Messenger. Moving on, it is also logical that if tens of thousands of chat client users actually need a Yahoo Invisible Detector, then also many are looking for a Gtalk invisible detector as well.
Unfortunately for those who are looking for an Gtalk invisible detector we have to answer, that we do not have any such service at the moment. In the matter of fact we have done our research into this matter, and currently there isn’t any invisible Gtalk detector service anywhere on the World Wide Web. But we have very good news though for those who want to check whether a Gtalk user is invisible or offline.
Anyone can detect invisible Gtalk users their selves by using a trick that is available due to a bug, or vulnerability, in the Gtalk system. In order to go around it and detect invisible Gtalk users, you first have to be logged in to your Gtalk client or into your Google mail (firstname.lastname@example.org) in your browser. If you want to check someone in your contact list whether he/she is “invisible” or really offline, you have to send a message to him/her. If you will get a feedback message stating that “>Contact name< did not receive your message” than the person you have checked is really offline. In case that you will not get any feedback message of any kind, than the contact is “Off the record”, which in big G.’s language means that he/she is invisible. The downside of this invisible Gtalk detection is that you have had to chat with that person before in order to be able to check whether the user is invisible on Gtalk or not and to send a message to the regarding person which will transform the Invisible Gtalk Scanner into a visible one.
