Treat these as three different URL outcomes, not three different people. After a Medium username change, the old profile link stops showing the profile, old story URLs redirect, and earlier mentions may still point to the profile. A current public profile link or the author's voluntary confirmation can clarify the destination, so ask for a voluntary current author link instead of inferring that a redirecting story, a failing old profile URL, and an old mention belong to separate writers.

Three URL outcomes, one likely author
A redirecting story link, a broken old profile address and an out-of-date mention can all sit around a single author whose handle changed. The useful move is to record each outcome plainly rather than turn the differences into a story about multiple people. A redirect says the destination moved; a failed old profile says that address no longer shows the profile; a mention says an older text still links where it linked before. None of those observations identifies who is behind the current page, and none proves intent. [Medium Help: profile URL schemes and username changes]
What the checked documentation actually says
The Medium help documentation describes supported profile URL forms and the effects of a username change. It notes that the old profile link stops showing the profile, old story URLs redirect, and earlier mentions still link to the profile. It also notes that enabling a subdomain redirects the earlier profile and story URL scheme. This is not a universal redirect rule, so do not generalize one outcome to every URL you find. Read each address as its own observation with its own limit. [Medium Help: profile URL schemes and username changes]
- Write down each URL you tried and what you saw at that moment.
- Mark which outcome is a redirect, which is a missing profile, and which is an unchanged mention.
- Avoid deciding that different outcomes mean different authors.
Separating observation, limit and action
Keep the three columns apart in your notes. An observation is only what the live page showed on the day you checked. A limit is what that observation cannot tell you, such as whether the author still uses the account or who currently controls it. An action is the practical next step you choose, usually asking the author for a current link rather than refreshing and guessing. This keeps a redirect from being read as proof of activity and a failed profile as proof of anything else.
| observation | limit | next step |
|---|---|---|
| A story URL redirects to a live page | Does not confirm the current author profile address | Ask for a voluntary current author link |
| The old profile URL no longer shows the profile | Does not identify who runs the current page | Record unavailable and stop at that boundary |
| An old mention still links to a profile address | Does not prove the author is active there now | Treat the mention as historical, not current |
Requesting a current author link
Ask once, plainly, without pressure: you found an older mention or a redirecting story and would like the current profile address the author prefers. A voluntary link from the author is more reliable than any inference from URL behavior. Keep the request short, and do not imply wrongdoing because an old address failed. If the person does not reply, leave the matter there rather than building a case from redirect patterns.
- Send one clear request for the current author link.
- State what you observed without interpreting it.
- Do not chase alternative profiles as substitutes.
When the link is not available
If no current link is offered, record that the current address is unavailable and stop at the access boundary. Use the platform's official current help pages if you need to understand URL forms, and treat the matter as closed until the author shares something themselves. Do not fill the gap with assumptions about multiple accounts, hidden identities or changed ownership. Behaviour and message content are separate questions from whether a URL resolves.

A couple more questions
Does a redirecting story URL prove the old profile belongs to the same person?
No. It shows the destination moved; it does not confirm identity or ownership. The checked documentation says old story URLs redirect after a username change, so treat the redirect as an outcome to record, not proof of who is behind the page.
Why can an old mention still link to a profile that no longer works?
An earlier mention keeps the link it was written with. The documentation notes that earlier mentions still link to the profile, while the old profile link stops showing it. The mention is historical text, not a live confirmation of the current address.
What should I ask the author instead of guessing?
Ask once for a voluntary current author link. Keep the message neutral, say what you observed, and do not suggest that the URL outcomes mean anything about honesty or intent. If no link comes back, record unavailable and stop.
