The use of social websites for personal and commercial purposes is widespread, and there is a tendency to ignore the disadvantages of media and focus only on the advantages. However, there are several disadvantages to using social media, including social, psychological, and criminal issues. Users could be scammed, cheated, or waste a lot of time without positive results. Young users may not discover particular real-life skills if they rely too much on social media. It makes some people hate social media and then decided not to use social media. According to the thinkbiganalytics page, some people in developed countries also hate social media even though it becomes more accessible there. These are some adverse effects of using social media overly;
Fraud and Deception
People need to register themselves before using social media. It means that they need to input some information regarding their privacy. However, this kind of information could be a danger for users. This information is then used to steal, make money, or commit other crimes. Therefore, social media could bring people to encounter fraud and deception.
Privacy Issues
There are crucial privacy issues associated with social websites. It is not always clear who can scan your profile and personal information. An embarrassing photo of you drunk at a party could be seen by family or friends, or careless comments about your work could be discovered by your employer.
Spam
Industry over-promotion and unsolicited advertising can be a constant theme. Out of a desire to make money, social media sites can be over-commercialized. Other users may also generate spam that is automatically generated and posted via “bots.” Individuals or companies are always trying to irritate users to push products and services.
Scam
The appearance of “fake news” has been a big problem lately, as a lot of “factual” information in social media turns out to be false or misleading. Sometimes they are poorly researched, but there can be threatening intentions behind them. Instead of elevating the human experience, social media has encouraged the number of false details people think.
Echo Chamber
Algorithms analyze users and provide them with messages that match their current opinions. Users share messages with like-minded men and women. Instead of bringing people together, social networks tend to reinforce social divisions rather than bridge them.
Information Overload
There is a sense of “information advice.” Users are exposed to enormous amounts of advice and data, but little is learned from it. People are overwhelmed with information and the benefits are minimal. Instead of reading long articles, people are increasingly shifting through short clips of advice in the form of memes, images, short videos, or other short messages. Besides, it may be possible for unscrupulous people to find out a person’s contact details, location, and social media references or send them threatening messages. People may monetize themselves not only with words but also with photos and other embarrassing pages. Therefore, it leads people to encounter bullying or harassment.
Time-Waster 
Social media can also be a big time-saver. Whether at the office or in your free time, sometimes you spend several hours on social media without reaping any obvious benefits. Not only can mundane things like family chores be neglected, but livelihood opportunities, school performance, and physical health can also be affected.
Psychological Issues
Some psychologists had expressed concern that social networking sites were replacing real-life relationships, with negative consequences. Children and young people of both sexes are particularly at risk, as they may never fully develop their social skills if they only use social websites on their computers. Social networking can also lead to mental health problems such as depression. Besides, they have raised concerns that many young people are replacing social websites with real-life relationships instead of learning vital skills to lead a happy and productive lifestyle. Therefore, people could utilize social media better.
