What are the main restrictions to p2p file sharing?

The main restrictions to peer-to-peer (P2P) file sharing include copyright laws, which prohibit the unauthorized distribution of copyrighted material. Many jurisdictions enforce these laws with penalties for users who share or download pirated content. Additionally, internet service providers (ISPs) may implement throttling or blocking measures against P2P traffic to manage bandwidth and comply with legal requirements. Lastly, security concerns, such as malware and privacy issues, often deter users from engaging in P2P sharing.
