1. Your online chat name should never contain your full name.
Illusion [34]

The correct options are as follows:

1. TRUE.

Your online chat name is your identity, which you use on the internet to communicate with your old friends and new friends, who you have just met and who you probably haven't met personally. It is of utmost importance that you don't use or reveal your full name online. This is because, your full name is the only thing some hackers need to get all the information they need about you. Through that single information, they can cause great havoc for you, like emptying your bank account, using your identity to commit fraud, stealing your email password and sending fraud messages through your box, etc.


2. D.

It is safe to tell an internet friend your favorite music. That is a relatively non important personal information that you can share with anybody. Such an information can not be used against you in any significant way. But sharing personal information such as full name, address and phone numbers can be very dangerous indeed if such information is shared with the wrong person.
