Sharing an address can amplify an unsupported claim, so context should travel with the link rather than disappear.
Identify who made the claim
Record the original publisher instead of citing only the page where the link was found.
If the source cannot be traced, say so plainly and avoid presenting the address as verified.
Preserve the claimed role
A primary URL, mirror, historical address and discussion link are different claims.
Do not relabel one role as another merely to simplify a post or status update.
Attach a review date
Every shared conclusion should state when the evidence was checked.
A timestamp helps readers recognize that a Mars Market link can become stale after publication.
Include uncertainty and limitations
Explain missing ownership evidence, unresolved redirects or conflicting sources in concise language.
Transparent limitations are more useful than a confident label unsupported by the record.
Prefer guidance over destination promotion
When verification is incomplete, share the review method rather than an actionable destination.
This reduces accidental amplification while giving readers a repeatable way to evaluate future claims.
