Is it a hack: chatroulette individual locking on to my IP or video feed

[meep69]

So while on chatroulette I found i was in between 'partners' when what did i see but someone was texting me. So I started talking back while it was searching for a new random. the person kept right on talking/texting answering what I was talking about. I asked how they were doing that but no answer they kept changing the subject. So I started hitting the next button thinking it was no really what I thought and sure enough it is. Apparently the individual is so how locking on to my ip or video feed and is able to keep track of me even though I am talking or viewing someone else.

Can someone please explain this? How is this doen and how do i do it?

Thanks in advance
