In light of the rapid proliferation of technology, individuals now have the ability to share their personal data online for communication and financial purposes. While this trend may offer potential benefits, they are eclipsed by the substantial drawbacks that users face. Admittedly, there are definite advantages to updating personal information online. To begin with, when accessing various networking websites, cookies software collects small pieces of data, including users' preferences and their associated online activities, in order to improve the web browsing experience. This personalized browsing experience enhances user satisfaction and efficiency. Additionally, maintaining a database of customer information enables businesses to gain valuable insight into market dynamics and adjust their operations accordingly to boost sales. For instance, major online retailers such as Amazon or JD.com often analyze consumers' online shopping behavior to target them effectively and offer personalized incentives to facilitate purchases. Notwithstanding the aforementioned benefits, the act of posting private information online brings about greater demerits. The foremost problem is the heightened risk of privacy invasion when personal data is stored on the internet. Unaware users may unknowingly fall prey to anonymous hackers by clicking on compromised links, thereby compromising their security settings. Consequently, cybercriminals can easily steal sensitive information, such as contact details or bank accounts, and exploit them for illicit purposes. Furthermore, the storage of personal data online, including phone numbers, can lead to significant disruptions for users. The influx of unsolicited calls not only annoys and distracts individuals from their intended tasks but also diminishes their overall productivity. For instance, the incessant influx of unsolicited junk mail or telemarketing calls, initiated by salespeople or automated systems, serves as a direct intrusion upon people's privacy. In conclusion, while putting personal information online does bring some benefits , I am convinced that the drawbacks accrued from doing this are far weightier including the potential privacy invasions and incessant disturbances that users may face.
