Facebook and twitter were created firstly for communicating between people. The communication, exchanging information, and overspreading knowledge were very acceptable social media goals. These sites used to offer great opportunities for users to express themselves, share their thoughts and take part to form a new community. Via social networking service, people posted and interacted with messages all over the world. Due to such great sites, the world becomes as a small village.
Later on, those sites divert onto financial market area. Those sites devote their works to take advantages of advertisements and become moneymaking very quickly.
The strong influence of advertisement of those sites on people's mind are very dangerous because there is no norm would limit their advertisements as long as you can pay money. Anyone can polish criminals or defame righteous when he pays money to those sites. Actually, the sites display the materials without even sure if the substance might be Photoshopped, faked or contained fallacy.
They don’t verify the videos or images, so many good concepts might be blackened by the adversarial or bad thoughts might be circulated. The amazing development of photoshop enables people to do whatever they want because there are no social, personal or professional ethics when someone advertises in general social media.
Unfortunately, the epidemic of sectarian violence, growing of racialism, civil wars and spreading of radicalism all these plights have been prevailed recently as a result of cupidity of social media sites.
It seems to me, if the social media sites don’t apply advertising ethics as ruling standards, the humanity will steepen to a dark slide way.
