There are several ways to report spam on Tumblr:
- From posts on the web: From the dashboard or a search results page, click the share menu (paper airplane) at the bottom of the post, and click “Report.”
- From blogs on the web: Report an entire blog by hovering over the blog's avatar, clicking the little person silhouette, and clicking “Flag this blog.”
- From messages in the app or on the web: Tap or click "Mark as spam" under the spammer's first message. Note that "Mark as spam" won't appear if it's somebody you follow, or somebody you've already had a conversation with.
- From fan mail on the web: From the inbox, click the three dots at the bottom of a spammy message and choose “Report.”
If you don’t have access to a computer at the moment, you can use a mobile browser’s desktop view to report spam following the steps listed above. To get to the desktop view in iOS, open Safari and visit tumblr.com, log in, tap the share icon (little box with an arrow) at the bottom of the screen, and tap the gray “Request Desktop Site” button. On Android, open Internet or Chrome and visit tumblr.com, log in, tap the three dots icon in the top right-hand corner of the screen, and check the “Desktop View” box.
