First classify the public artifact: an original post belongs to the blog that published it, while a reblog with commentary is a re-share where the reblogging blog adds its own visible text. Tumblr's documentation says tag search includes original posts, whereas reblogs with added commentary can appear in regular search but not tag search. So a missing tag result is a search-surface difference to record, not proof that the post was deleted or that anyone is hiding something.

Classify the artifact before searching
Open the public post you already have and read its structure. Look for visible re-share cues, a prior post body, and added commentary from another blog. Do not infer anything from avatars, usernames or style. The question is only whether this artifact is an original post or a reblog with commentary, because that classification changes which search surface is relevant. If the artifact is private, ambiguous or mismatched, record that precise limit and stop rather than attempting access or identification.
- Save the public source link exactly as found.
- Note visible re-share cues and any added commentary in your own words.
- Write 'original' or 'reblog with commentary' only when the page structure supports it.
Compare tag search with regular search
Tumblr's help documentation states that tag search includes original posts, while reblogs with added commentary can appear in regular search but not tag search. That means a public reblog may be discoverable through one surface and absent from another without any deletion. Search each surface separately and record what you actually saw, the query used and the date. Keep the public source link beside your notes so the observation stays traceable.

| observation | limit | next step |
|---|---|---|
| Original post visible on the blog but absent from a tag query | Tag search is documented as including original posts, but a missing result does not establish that the post never existed | Record the surface, query and date, then recheck regular search before drawing any conclusion |
| Reblog with commentary absent from tag search | This can match the documented indexing difference between tag search and regular search for reblogs with commentary | Check regular search separately and label the result a surface difference, not a deletion |
| No result on either surface | Absence of a result is not proof of deletion, privacy or intent | Stop the inference and note the limit beside the preserved public link |
Preserve the public source link
Keep the exact public URL of the artifact in your notes, without changing it into a shortened or paraphrased reference. The link is what lets you separate what you observed from what you later assume. If the link later fails to load or resolves to something different, record that as a precise observation rather than interpreting it. Do not seek private records, cached copies from private accounts or any workaround to recover content you were not permitted to view.
Mark search-surface differences instead of alleging deletion
Deletion, privacy changes and search indexing are different explanations, and a single missing result cannot distinguish among them. The documented rule that reblogs with commentary may appear in regular search but not tag search is enough to explain some absences without any deletion claim. Write surface-level observations such as 'absent from tag search on this date' rather than 'deleted' or 'hidden'. This keeps the note accurate and avoids accusing a blogger of removing content.

A small review worksheet
This worksheet is an editorial aid for your own notes, not a promised platform feature. Fill it in only from what is publicly visible and from your own search observations. The aim is to make each step reviewable by someone else and to keep the classification separate from the search comparison.
- Public source link exactly as found.
- Classification: original or reblog with commentary, with the visible cue that supports it.
- Search surface checked, query used and date.
- Observed result stated plainly, without adjectives about intent.
- Limit recorded, for example private, ambiguous or mismatched.
- Decision: continue comparing surfaces, or stop at the boundary.
When to stop at the boundary
If the source is absent, private, mismatched or ambiguous, write that exact limit and stop. A bad or missing result is not evidence of intent, identity or activity. Do not attempt private-account access, do not treat a username or image match as verified identity, and do not contact strangers to ask what happened. A public username or image can at most lead to public profile clues, with no guaranteed coverage and no proof of identity or current activity.
- Record the limit in one sentence and end the review.
- Do not upgrade a missing search result into a claim about the person.
- Keep the public link with the note so the limit can be rechecked later.
A couple more questions
Why might a public reblog not appear in Tumblr tag search?
Tumblr's help documentation says tag search includes original posts, while reblogs with added commentary can appear in regular search but not tag search. A missing tag result for a reblog is therefore consistent with a search-surface difference and does not by itself show that the post was deleted.
How do I tell an original post from a reblog with commentary?
Read the public page structure: a reblog re-shares a prior post body and may show added commentary from the reblogging blog, while an original post is published by the blog that owns it. Base the label only on visible structure, and record 'unknown' if the structure is ambiguous.
What should I do if the artifact is private or I cannot match it?
Record the exact limit, such as private, mismatched or ambiguous, and stop. Do not seek private records, bypass access controls, or attempt to identify anyone from a username or image.
Does a missing result prove the post was deleted?
No. A missing result is an observation about one search surface at one time. Deletion, privacy changes and indexing differences are separate explanations, and a single absence cannot distinguish among them.
