Anonymous Online Posting No Shield Against Doxxing Prosecution, Expert Warns
On.cc · 1 SOURCESabout 1 hour ago5 MIN

Summary
Technology experts warn that anonymous online posting provides no protection against prosecution for doxxing, as digital footprints including IP addresses, timestamps, and device information can be traced by law enforcement through telecom providers and technology crime investigation techniques. Under the revised Personal Data (Privacy) Ordinance, doxxing and sharing others' privacy without consent constitute criminal offences carrying serious penalties including potential imprisonment. The Privacy Commissioner can investigate, prosecute, issue removal orders, and work with law enforcement to protect victims.
Key Points
- IP addresses, connection times, and device information leave digital footprints that law enforcement can trace through telecom providers and content suppliers
- Overseas platforms and VPN services increase investigation difficulty but do not provide absolute anonymity, as anonymous identities are not a shield
- Francis Fong (方保僑), Honorary President of the Hong Kong Information Technology Commerce Association, emphasizes that the online world is not a legal vacuum and doxxing constitutes a criminal offence
- Young people should never violate the law impulsively, as a criminal record will affect lifelong prospects
- The revised Personal Data (Privacy) Ordinance added provisions targeting doxxing, covering specified harms including harassment, threats, psychological trauma, and reasonable safety or property concerns
