Why this happens

Group chats produce diffuse responsibility. The original sender posts once and dozens of participants can save, screenshot, and re share the content within minutes.

Most group chat leaks involve a participant the victim knows personally. The initial sharer is rarely the same person as the original perpetrator, which complicates the legal trail.

Legal framework in Czech Republic

Trestní zákoník § 354 (nebezpečné pronásledování) plus § 184 (pomluva). Up to 1 year imprisonment under § 354. Up to 3 years for aggravated stalking patterns.

The Czech Republic prosecutes NCII through the dangerous stalking provision of § 354 combined with personality protection rights under the Civil Code, with the ÚOOÚ enforcing GDPR erasure obligations against hosts.

Evidence to preserve

Do not: Do not leave the group chat before screenshots are preserved. Once removed you may lose access to evidence that the chat history will only show to current members.

Five step removal process

  1. 1

    Preserve all evidence first

    Screenshots of the message thread including all participants and timestamps. The chat application name and any group identifier or invite link.

  2. 2

    File the § 354 trestního zákoníku criminal complaint

    Report to local police or the national cybercrime unit. Stopline.cz can assist.

  3. 3

    Submit an erasure request under GDPR Article 17 (right to erasure)

    Each major platform has a designated data protection contact. The request must cite the legal basis and identify the URLs. The platform has 30 days to respond. ÚOOÚ accepts complaints for non compliance.

  4. 4

    Run a biometric scan to find every additional copy

    Content posted to one platform is rarely confined to one platform. ScanErase identifies every current hosting location in a single scan, including mirror copies and AI generated variants.

  5. 5

    File TAKE IT DOWN Act notices for covered platforms

    Use your scan report to file the federal 48 hour notice yourself, in parallel with your domestic rights. The two regimes are cumulative, not exclusive.

Statutory citations to include in your complaint
