how can i know that a person is in invisible mode in messenger how can i find him out is there any software?

Answer 1

To find that the person is in invisible mode, sign in to yahoomail, add his/her name to ur address book(if not added already) and if he will be online if you see a face left to his name smiling (and bright) in your address book. else that face would look sad

Answer 2

No, and whatever advertises such a thing is trying to lure you in to spyware, spam, adware, pop-ups and more general malware. Would you want your exes harassing you while invisible?
