Among the various potentially illegal activities described by Andriy Slynchuk, five stand out as particularly serious violations of the law and ethical standards. First, using unofficial streaming services for accessing copyrighted content like movies and TV shows not only constitutes copyright infringement but also exposes users to potential risks associated with such platforms, including data theft. Second, utilizing torrent services to obtain pirated copies of copyrighted material not only deprives creators of fair compensation but also perpetuates a culture of piracy. Third, sharing copyrighted images without permission or proper attribution violates the rights of content creators and undermines the value of their work. Fourth, sharing personal information such as addresses or photos of others without consent can lead to privacy violations and even harm, especially in cases of cyberbullying or stalking. Finally, engaging in illegal searches on the internet, such as seeking out child pornography or bomb-making instructions, not only breaks the law but also poses significant risks to individuals and society at large. These offenses are serious because they infringe upon intellectual property rights, and privacy rights, and may even facilitate criminal activities, highlighting the importance of upholding legal and ethical standards in online behavior.
