Tumblr’s 30-Hour Attribution Riot

Note: I was alerted to this story and got much of the information in this article from this video by YouTuber (and Tumblr user) STRANGE ÆONS. I highly recommend checking out that video. She also gets credit for giving me the idea for the title of this article.

Tumblr, as a website, has had a very long and checkered history. Founded in 2007 by David Karp, it was originally envisioned as an alternative to traditional blogging like Blogger and WordPress. The focus was less on traditional publishing and more on creating an internal community that reblogged and shared content within the ecosystem.

That idea made it incredibly popular in the early 2010s. Yahoo! would famously pay $1 billion for the site in 2013 in one of the most high-profile acquisitions at the time.

However, since then, Tumblr has had a pretty rough run. Most of the times it has “broken containment” and made public news has been for the wrong reasons. That includes the failure of Dashcon in 2014 and the site’s banning of adult content in 2018 and the user backlash over it.

As users and revenue declined, Tumblr was eventually acquired by Automattic, the company behind WordPress.com, for just $3 million in 2019.

But, while the site is nowhere near its halcyon days of the early 2010s, it is still has a large following and millions of active users. They, in general, love the site as much for what it isn’t as for what it is. It’s a truly unique place on the internet that is neither a social network nor a traditional publishing platform.

So when the staff of Tumblr decided to change a key feature of the site, it was met by a user revolt. The change was overwhelmingly unpopular, leading to the original post getting over 300,000 notes and the site’s support page crashing.

What was that change? It was a relatively simple change to how attribution (and thus conversation) works on the site.

Attribution, Tumblr and Reblogs

On Tumblr, notes has a less-than-obvious definition. When you post something on Tumblr, users can interact with that post by liking it, reblogging it or commenting on it. The number of those three things combined is the number of “notes” that the post has.

So, for example, if you post something that gets 100 likes, 20 reblogs and 10 comments, the post has 130 notes. However, where things get complicated is with reblogs.

Historically, reblogging a post on Tumblr was simply a Tumblr user putting the same post on their blog, even if the reblogger added something to it. The note count would carry with it. This meant that every reblog of a post had the same note count as the original post.

This means that a relatively small Tumblr user could share a post and, even if it’s only picked up by a few others, it could still rack up amazingly high note counts if one of those reblogs caused it to catch fire. So, even though the original post might only get a few reblogs, it would still show the hundreds or thousands of notes that it obtained across Tumblr.

On March 16, 2026, Tumblr announced that they were changing that.

The title of the post simply read, “Reblogs in a chain now get their own notes.” This meant that, if a user reblogged a post, it would start with zero notes and would function as a totally new post. Going back to that small Tumblr user, they would only see the handful of reblogs even if one of those reblogs ended up getting hundreds of thousands of notes elsewhere.

According to the post, the goal was to give credit to reblogs that add a significant amount to the original post. Users, however, were not happy with the change.

To be clear, there is some precedent here. X, (formerly Twitter) does keep the same comment, repost and like counts for straight reposts. But posts that quote the original are given their own count, starting a new chain. Facebook also does something similar.

But precedent or not, Tumblr’s users were overwhelmingly against the change. They kicked off a 30-hour-long “riot” that overloaded the site with memes, gifs and other content protesting the change. Users also filed mass complaints with the sites support page, causing it to crash.

In the end, Tumblr reversed the change. In their post about the move, they said, “Your feedback in comments, emails, and especially reblogs, made clear that the rollout created problems we need to address before moving forward. We also should have communicated this differently from the start, and we didn’t.”

However, they did say that “We still believe there’s a better version of how reblogs can work. One that gives every voice in a chain the credit it deserves. But we want to get there with you.” This means that, most likely, some change is still forthcoming.

Two Major Questions and Takeaways

This leaves two major questions, especially for those outside of Tumblr. First, why did Tumblr make this change in the first place? Second, why did it fail?

To me, as an outsider, the answer to the first question is pretty obvious: Tumblr wanted to reward and promote users with large, organic audiences.

As I wrote yesterday discussing the Theranos scandal, attribution is a powerful tool for reframing how a particular work is perceived. Theranos falsified attribution on their studies to make them seem more valid. However, that perception and that reward flows both ways. This is why people commit traditional plagiarism, because they want to take credit for work they didn’t do.

To be clear, this isn’t a plagiarism story, at least not in the traditional sense.The original poster would have been attributed. However, the “rewards” of the attribution, namely the note count, would have flowed to the biggest rebloggers, not necessarily the source.

While Tumblr’s goal to reward users who add value to posts is noble, as we’ve seen on social media platforms, that’s rarely how things pan out. It’s much more common that bigger accounts reap bigger rewards regardless of the value they add. For example, on Facebook it’s been such a big problem that they have had multiple initiatives to fight unoriginal content.

Ultimately, Tumblr was likely hoping to reward users for promoting Tumblr content off the platform. The system Tumblr has now rewards posts that go viral within Tumblr itself. By making it more difficult for smaller accounts to rack up notes, they were hoping to encourage users to push their content off site and bring new users to the platform.

If the only way to expand your reach is to grow your local audience, it motivates users to bring more people to the platform as well as seek out new followers within Tumblr.

But that was the big mistake for Tumblr. Tumblr users simply don’t care about that. Those who care about organic reach are on X, Facebook, Instagram, TikTok, Substack, LinkedIn and a thousand other places. Tumblr, in many ways, is an inside joke shared between its millions of users.

As STRANGE ÆONS pointed out in her video, this makes Tumblr users very resistant to any change, especially a change that would make the site more similar to other places (and thus less special).

The only reason Tumblr has the audience it does is because users get something from there that they don’t get anywhere else. Tampering with that is a recipe for disaster.

Bottom Line

The connection between attribution and a particular work is a two-way street. Authorship and attribution helps contextualize a work, but the author is also rewarded when the work succeeds and does well.

Social media platforms have a long history of messing with authorship and attribution as a way to steer rewards where they want to. When used in conjunction with algorithms and other selection systems, platforms can reward the content they want and devalue the content they don’t.

Tumblr, whether they realized it or not, was trying to make a shift in that dynamic. Unfortunately for them, it’s a shift that went against the values of their users. The users like the current system because it rewards original posters and encourages a type of conversation that can be organically branched in a million different directions.

In the end, I have to agree with STRANGE ÆONS, Tumblr’s management doesn’t understand Tumblr. To be fair, I don’t understand Tumblr, but I’m also not the one tasked with steering the ship.

Since this fallout, Tumblr’s management announced that they will be forming a new “Advisor Board” of the top Tumblristas. They also launched a new survey to better understand how users use the site.

However, I don’t think this strategy is likely to succeed. It makes the same mistake of focusing too heavily on the “biggest” users. One of the things its users like is that the dynamic of the site is chaotic. Sure, some users have a bigger following than others, but the focus is much more on the platform as a whole.

Tumblr’s users don’t want the site to be X, Facebook or WordPress. They want it to be Tumblr, even (or especially) if that isn’t the normal or most profitable way to operate such a platform.
