THE INTERNET
.... ITS BAD USES....
SOCIAL ENGIRNEERING
This is when people try to get information out of you by pretending they are someone that they are not! They might try to spam you with messages saying 'hi I think your cool' which encourages you to become friends with them but DON'T if you do they could make a communication that is a scam or worse... a virus! If you do by accident click on a link, check the web address and see if it is something you know.
PERSONAL INFORMATION
You will often be asked for personal information when on a site BUT BE CAREFUL, some sites may ask you for this information just because they want to STEAL this information and maybe even pretend to be you!!! :D ESPECIALLY don't put your date of birth unless you really need to... Banks will never ask you for this kind of information, D.O.B, address, schooling so its simple, don't give it to them!
AGRESSIVE PEOPLE
Some people may be more aggressive online than they would ever dream of being in real life! Just ignore them and they'll stop harassing you, or even better REPORT IT! Whatever you do, don't reply or send aggressive messages back, don't let them know that it is hurting you. Tell someone you can trust what they are saying and screen-shot when necessary. (control, shift and print screen on a computer)
