Andriy Slynchuk describes several internet activities that can be considered illegal, with five standing out as the most serious. First, collecting information about children is a major concern, as it violates privacy laws and exposes minors to harmful content. Children are unable to consent to such data collection, making it especially unethical. Second, sharing sensitive information like passwords, addresses, or photos without consent can lead to dangerous situations, as malicious individuals may exploit this data. Third, using someone else’s internet network without permission is a violation that could lead to illegal activity being traced back to the network owner. Fourth, illegal searches on the internet, such as researching ways to commit crimes, can trigger alerts to authorities and put others at risk. Lastly, online bullying and trolling can cause severe psychological harm, potentially leading to real-life consequences.
