Out of the eleven things internet users do that may be illegal, the five that I think are the most serious violations are: Sharing Passwords, Addresses, or Photos of Others, Recording a VoIP Call Without Consent, Using Other People’s Internet Networks, Collecting Information About People Younger Than 13 and Illegal Searches on the Internet.
Regarding Sharing Passwords, Addresses, or Photos of Others, sharing that information with the intent of causing harm to someone would probably at a minimum make you accessory or complacent to the crime. In regards to Recording a VoIP Call Without Consent, that’s no different than recording or taking photos of someone without consent. Using Other People’s Internet Networks is, as the article itself says, stealing. There isn’t any other way to really put it. Collecting Information About People Younger Than 13 feels like it is too close being preying on children than anything, which is illegal as well. Illegal Searches on the internet is self-explanatory: It’s Illegal.
