HOW TO BE A RESPONSIBLE NETIZEN?


WHAT IS A NETIZEN?

v  A netizen is someone who uses the internet. Most of these people who we call netizens are millennials or generation y, but, by simply searching something using the internet you have simply become a netizen.

v  There are also responsibilities you have as a netizen because the internet is a powerful weapon or tool that can be used against another netizen.

TIPS ON HOW TO BECOME A RESPONSIBLE NETIZEN

ü  BE AWARE OF WHAT YOU POST ONLINE
o    by simply posting something can affect yours or other people's lives that's why as a netizen you should be aware of what you post online

ü  DO NOT ENGAGE IN CYBER BULLYING AND OTHER INTERNET CRIMES
o    bullying is against the law and can make a huge impact on a person's life some even consider committing suicide just to escape bullying.

ü  READ BEYOND THE HEADLINE
o    Before sharing stories on social media, make sure to check if the source is reliable and if the information can be backed up with evidence. Another important response is to check the date and make sure the post is not outdated.

ü
REDUCE THE NOISE. DO NOT SHARE UNVERIFIED REPORTS ON SOCIAL MEDIA
o    Social media can easily get flooded in times of emergencies. Help reduce the noise by not spreading unverified information on social media – especially those that do nothing but provoke fear in the community.      

ü  MAKE YOURSELF GOOD ONLINE
o    For most of us there aren't too many ways of making yourself look silly in front of hundreds of people, but sending a badly spelled, grammatically incorrect, thoughtlessly put together e-mail message is one.




Always remember that the internet is a powerful tool and should not be abused and also remember to never criticize someone using the internet and to think before you click.
