I log on to skype invisible and someone I don't want to talk to sends me a message 30 seconds later. I know you can send someone an IM/call to test if someone is invisible, how did this person know I had come online in the first place? (and no it was a historic message that came in as I logged in)
I've been google searching this, but there is no clear answer.
