Executive summary

If you accidentally encounter illegal content online, immediate steps typically recommended by legal experts and regulators are: stop viewing or downloading the material, preserve minimal evidence for reporting (if safe), and report it to the platform and appropriate authorities or “trusted flaggers” rather than sharing it further (Ofcom/Online Safety Act guidance and EU “notice and action” rules) [1] [2]. Available sources do not give a single consolidated “do/don’t” checklist for individual users, but they do emphasize prompt takedown/notification duties for platforms and safer reporting channels for priority criminal content such as child sexual abuse material (CSAM) [3] [1].

1. Stop interacting — don’t download or redistribute

Regulators and commentators stress that platforms and services must remove illegal material quickly and limit its spread; by analogy, a user’s first practical step should be to cease viewing, avoid downloading, saving, or forwarding the content, because further possession or distribution can increase legal exposure and frustrate platform takedown efforts (Ofcom’s illegal harms focus and duties for platforms show urgency around removing illegal content) [1] [4]. Available sources do not provide criminal-law advice for every jurisdiction; local laws determine whether mere viewing or temporary caching carries legal risk — consult local authorities or a lawyer for jurisdiction-specific criminal liability (not found in current reporting).

2. Preserve minimal evidence — but do it safely and legally

Regulators expect platforms to act on reports; to help them, it may be useful to note the URL, timestamps, and any contextual metadata for reporting purposes. Ofcom’s and the EU’s “notice and action” frameworks presuppose accurate reporting and trusted flagger channels to speed takedowns, which depend on details such as URLs and timestamps [2] [3]. However, do not create copies of the illegal files or distribute screenshots to third parties — doing so can itself spread the illegal material and possibly create legal exposure (sources emphasize removal and avoidance of further spread rather than instructing on making private copies) [1] [3].

3. Report promptly to the platform’s takedown mechanism and/or a trusted flagger

The Digital Services Act/related EU guidance and national schemes emphasize “notice and action” procedures and the role of trusted flaggers and content managers to fast‑track removal of illegal content [2] [5]. Ofcom’s Online Safety Act regime similarly prioritizes reporting to platforms and regulators for illegal harms like CSAM; users should use the service’s reporting tools or the platform’s designated channels so providers can begin the lawful takedown processes required by regulators [1] [4].

4. Notify law enforcement or specialist hotlines for priority criminal content

When the material involves priority criminal content — for example, child sexual abuse material — regulators and enforcement programs make clear that platforms and authorities treat these reports as urgent; Ofcom has identified CSAM as an early enforcement priority and launched programmes focused on file‑sharing services [3] [1]. Many jurisdictions also have specialist hotlines or police units for reporting such crimes; available sources show regulators expect such escalation but do not list country‑by‑country hotlines — consult local law enforcement websites (not found in current reporting).

5. Don’t try to “self‑police” by circumventing platform systems

The policy conversation in the EU and UK centers on formal notice-and-action workflows, trusted flaggers, and regulatory enforcement rather than ad hoc user interventions [2] [4]. Bypassing these channels — for instance, posting the content to call attention to it — risks amplifying illegal material and undermines the quick removal that regulators require platforms to provide [2] [1]. Platforms are increasingly required to use technical measures (perceptual hashing, automated matching) to detect and remove known illegal files; users should let those systems and official channels do the takedown work [3].

6. Consider privacy and evidence retention if you are an affected victim or witness

Regulatory materials stress the protection of victims and the need for platforms to reduce harm to individuals; if you are a victim or witness, preserve relevant information in ways that protect your privacy and follow guidance from specialised support services or law enforcement (Ofcom and the OSA emphasize protection of children and victims in enforcement priorities) [1] [4]. Available sources do not provide step‑by‑step victim guidance for every situation; seek local victim‑support services or legal counsel where possible (not found in current reporting).

7. Broader policy context and competing views

European and UK regulation has pushed platforms to prioritize rapid removal and robust reporting systems [2] [4], while civil‑liberties advocates warn that aggressive blocking/takedown schemes risk over‑blocking and collateral harm — for example, documented cases where broad site‑blocking swept up legitimate services [6]. That tension shapes why regulators emphasize transparent notice-and-action procedures and trusted flaggers to reduce wrongful removals [2] [6].

Final note: these sources set expectations for platforms and regulators and imply sensible user behaviour (stop, don’t share, report through official channels), but do not replace legal advice. For jurisdiction‑specific criminal or civil liability questions, consult a qualified lawyer or local authorities; that detail is not provided in the current reporting (not found in current reporting).
