Leaving a secondary group blog removes your membership from that shared blog, and the blog can continue with its remaining members and administrators. Deleting your account is a different action that removes the whole account, including your primary blog. Decide which one you mean before you touch any control; if the documented option is not visible, record it as unavailable and stop.

Name which thing you are leaving
A Tumblr account has a primary blog and can also create secondary blogs, and secondary blogs may be password protected or shared by several users. Because both live under one login, it is easy to say "I'm leaving" while meaning two different things. Decide first whether you are stepping out of one shared secondary blog or removing the whole account, and note whether that blog is shared with other users. [Tumblr Help: primary versus secondary blogs]
- Identify whether the blog is your primary blog or a secondary blog.
- Note whether the blog is shared with other users before deciding anything.
What leaving a group blog changes
A secondary group blog can have multiple members, and leaving it with other members still attached does not delete the blog; the remaining membership and administration carry on. Your departure is a membership change for one blog, while the blog itself continues as long as others remain responsible for it. If the blog appears to have no other members, or the control you expect is missing, record unavailable and stop rather than assuming an outcome. [Tumblr Help: group blog membership and attribution]
What account deletion reaches that leaving does not
Deleting a primary blog deletes the whole account, so it is not a substitute for stepping out of one shared blog. The two actions sit on different levels: one changes your place in a group, the other removes the account that holds your blogs. Primary and secondary blogs also differ in which social features they support, so a feature you relied on in one may behave differently in the other. Read the current official wording for your own account before choosing; if you cannot find it, stop rather than testing controls by trial and error. [Tumblr Help: primary versus secondary blogs]
Attribution and other people on the blog
Optional author portraits attribute posts to an individual member next to the blog avatar, and Tumblr advises getting members' agreement before showing them, since people may want their identities kept separate. Before you leave, decide what should happen to attribution tied to you and mention it to the people who remain. A portrait is a display choice on the blog, not a verification of the person behind it. [Tumblr Help: group blog membership and attribution]
- Ask remaining members what they will do with author portraits that point to you.
- Avoid treating any label or portrait as identity verification when reviewing the blog.
Keep observations, limits and decisions apart
A short written record keeps this decision clear. Put what you can see in one column, what it cannot tell you in another, and your next step in a third. This is a hypothetical example.
| observation | limit | next step |
|---|---|---|
| The blog lists more than one member | A listing does not show who is active or who administers it now | Confirm with the remaining members before you leave |
| Your name appears beside some posts as an author | A display choice does not verify identity | Ask what happens to that attribution after you leave |
| The control you expected is not visible | This may be an interface or availability difference you cannot resolve | Record unavailable and stop at the access boundary |
| You are considering deleting your account instead | Account deletion reaches your primary blog and the whole account | Re-read the official current help before proceeding |
Your stopping rule
Act only on settings that belong to you, and only on the shared blog you were invited to or created. If the documented control is missing, if you cannot tell whether other members remain, or if a step would require access you do not have, record "unavailable" and stop. Do not attempt workarounds or infer what happened from someone else's profile. If you need help, ask the people who share the blog for a voluntary current link to the official help.
- Decide first: leave the shared blog, or delete the account.
- If the expected control is absent, stop and record it.
A couple more questions
If I leave a shared Tumblr blog, does the blog disappear?
No, not by itself. A group blog with remaining members continues, and their membership and administration carry on after you step out. Your departure is a membership change for one blog, not a deletion of the blog or of your account.
Is deleting my Tumblr account the same as leaving a group blog?
No. Leaving removes your membership from one shared secondary blog; deleting a primary blog deletes the whole account. If your goal is only to step away from a group, account deletion is more than you need.
What should I do if I cannot find the leave option?
Record it as unavailable and stop. Consult the official current help for your own account, or ask a member of the blog to share a current official link voluntarily.
