[bulb1234]

Here is a specific question , please help me finding the answer.

Suppose that a person’s Yahoo email id is bulb1234@yahoo.com but he has made additional profiles on yahoo, one of them is tube23. Now the person logs on the messenger and than enters chatroom as tube23. Is there any way for a booter to see that primary id of the person, who is in chatroom as tube23, is actually bulb1234? Here I am not talking about nickname –the person can enter chatroom from tube23 id with a nickname lamp12 but it will be easy to see that his id is tube23-- my question is –will it be possible to see that his primary email id is bulb1234?

Is the above discovery possible in chatrooms or is it possible only from IM, or from none. Will it be possible to give the answer and explain the reason in very simple language?


thanks
