Danger of sharing personal information

1) I experience nothing on online activities.
2) I did not reveal my personal information online.
3) Personal information like hobbies, what pets I keep, my favourite TV programme, my favourite internet games, my favourite food and places I visited during the school holidays can be shared online but personal infomation about yourself example like your birth certificate. bank account number, home telephone number and home address cannot be shared.
4) Cyber pals can go into your account, hack your account and they could also purchase and buy things in the internet.
5) I will tell him or her that I cannot disclose.
