Internet users may engage in illegal and harmful activities. Cyberbullying and trolling are purposes of torturing, humiliating and harassing victims. This may result in significant emotional and psychological suffering, putting the mental health of others at risk and may ultimately result in self-inflicted harm or suicidal behavior. Another illegal activity is internet identity theft, which may result in theft or fraud. Through impersonation or misrepresentation of an individual another person violates privacy and trust, and faces serious legal consequences for both the impersonator and the person so misrepresented that such business would not be started and supported and would not be conducted untruthful and fraudulently. Searching the Internet for restricted content (pornography online) and hacking into databases (apart from medical databases) is also unlawful. Such activities breach intellectual property rights and undermine individual and economic security, via identity theft and data exfiltration. The sharing of passwords, addresses, or pictures without the consent of others is a breach not only of privacy but of people’s personal boundaries. Sensitive personal disclosure without authorization can lead to identity theft, cyberstalking, and harassment. As a last resort, attacks on someone else’s internet network without authorization are a violation of trust and a crime since they can include access to services or data to steal. These practices erode confidence, privacy and inflict financial and emotional damage. To deter cybercrime and emphasize the damage it inflicts on individuals and the community, there are ongoing laws under development and being passed to criminalize cybercrime.
