How many time when we open computer or phone and get in the social network. Expect for meet friend or relative, and we can see other people activity both existing or not in friend list. these activity are different like some friends are sad and other friends are happy.

In some country they ban facebook because they make problem in country like north korea,they block all social media because they don’t want to have social media and they want to live by themselves.

In social media people believe who is successful person will be in social media, and they are reject social media guideline a lot of these people most are use cyber space to commit an offence such as hacking, cyber fraud, cyber harassment and cyber impersonating.

In my opinion I think it’s have advantage and disadvantage, in advantage side is we can see new news or something we like , in disadvantage side is another people can peek our activity,I think facebook or another app such as IG , Youtube , twitch should add more fiction like before post facebook have to check that is illegal or not .Once the villain has been capture they should b din the jail all life because if we release the villain I think they will back to make mistake.
