What a claim record is How to read this page

One statement, bounded on purpose

The headline is a single claim that a named source supports. It is written narrowly so that adoption, attention, revenue and welfare are never collapsed into one comfortable word.

The three sections below the fold

What this does not establish is the boundary of the evidence. Counterevidence & uncertainty is what argues the other way. What would change the reading is the observation that would move it. A record missing any of the three is incomplete, not merely brief.

Primary routes are checkable

Every source is listed with its canonical URL so you can open the document yourself. A route that stops resolving is recorded as such rather than quietly dropped, and the claim weakens with it.

MWITA-RD-2026-020 · Evidence A · P1

UK Online Safety Act illegal-harms safety duties began applying on 17 March 2025 after the 16 March risk-assessment deadline, and Ofcom simultaneously launched an enforcement programme focused on child sexual abuse material risks in file-sharing services.

What this does not establish

Opening an enforcement programme is not a finding that every named or in-scope service violated the Act.

Counterevidence & uncertainty

Service scope, risk profile and proportionate measures are fact-specific.

What would change the reading

Track investigations, information notices, penalties, codes revisions and court challenges.
