Clarification for “Selection bias in a self-reported forum sample”: the point beginning “Discuss who chose to post, missing outcomes, unverifiable records…” belongs to the question as written. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: scope. Keep the stated question separate from any broader claim.
