Out of a provided list, I believe the top five most serious items are as follows (in no particular order): Bullying and Trolling, Collecting Information About Children, Illegal Searches on the Internet, Using Other People’s Internet Networks, and Faking Your Identity Online. The first, bullying and trolling, seems pretty self-explanatory. Any kind of bullying is wrong and could be considered a crime in severe cases. Even if the bullying is done without the perpetrator knowing the action is illegal, it is still done with malicious intentions. Collecting information about children and illegal searches can potentially go hand in hand. Children are one of the most vulnerable populations in society, and there is a reason laws are in place to protect them online. Unknowingly collecting information for mundane purposes, such as by using a survey without realizing the recipient’s age, can be excused (although still illegal). Illegal searches of inappropriate images of children, similar to cyberbullying, is done with direct malicious intent. Using other people’s network is essentially stealing that person’s property that they have paid for. Faking an identity online can be used for fraud purposes and other crimes. It can also be used to provide a false age to social media accounts, but as the article states, there are no laws against it.
