A bookmark preserves an address, not its ownership or status. Old bookmarks should be reviewed whenever the surrounding evidence changes.
Record when the bookmark was created
A saved date gives the link historical context. Without it, users may assume a years-old Mars Market address was verified recently.
Add a note describing the source and role claimed at the time.
Do not follow unexpected redirects automatically
A bookmarked domain can later redirect elsewhere. Compare the destination with a current, independently documented source before relying on it.
A redirect is a new observation that requires review, not proof of continuity.
Retire bookmarks visibly
Move outdated entries into an archive with a retired date instead of silently replacing them. This preserves the reason an old address may still appear in records.
An archive should not present retired links as active navigation.
Review after material changes
Nameserver changes, certificate changes, status incidents and source corrections are useful re-verification triggers.
A bookmark that passed an earlier review should not bypass a new assessment.
Use bookmarks as notes, not authority
The strongest habit is to treat a bookmark as a pointer to re-check. Current provenance and status matter more than the fact that an address was saved before.
This reduces the risk of stale Mars Market links being reused without context.
