We’re taking steps to protect against future interference in our political conversation by state-sponsored propaganda campaigns

Hi Tumblr,

We’re all grappling with the influence that state-sponsored disinformation campaigns can have on our political conversations—and how wide-spread that interference turned out to be. So please take a moment to read this, think about it, and talk about it.

Last fall, we uncovered 84 Tumblr accounts linked to the Russian government through the Internet Research Agency, or IRA. These accounts were being used as part of a disinformation campaign leading up to the 2016 U.S. election. After uncovering the activity, we notified law enforcement, terminated the accounts, and deleted their original posts. Behind the scenes, we worked with the Department of Justice, and the information we provided helped indict 13 people who worked for the IRA.

Now that the investigations are done, we want to let you know how we’re going to help protect Tumblr in the future and what you can do to help.

Here’s what we know about these accounts

The IRA employs more than 1,000 people who engage in electronic disinformation and propaganda campaigns around the world using phony social media accounts. Their goal is to sow division and discontent in the countries they target. What makes them so difficult to spot is that they’re not spambots. They’re real people who get trained and paid to spread propaganda.

As far as we can tell, the IRA-linked accounts were only focused on spreading disinformation in the U.S., and they only posted organic content. We didn’t find any indication that they ran ads.

Remember, the IRA and other state-sponsored disinformation campaigns play off our zero-sum politics. They want to drive a wedge between us so that we spend our time fighting with each other instead of building towards the future. We’ll be watching for signs of future activity, but the best defense is knowing how they operate and how to judge the content you see.

What we’re doing in response to the interference

First, we’ll be emailing anyone who liked, reblogged, replied to, or followed an IRA-linked account with the list of usernames they engaged with.

Second, we’re going to start keeping a public record of usernames we’ve linked to the IRA or other state-sponsored disinformation campaigns. We’re committed to transparency and want you to know everything that we know.

We’ve decided to leave up any reblog chains that might be on your Tumblrs—you can choose to leave them or delete them. We’re letting you decide because the reblog chains contain posts created by real Tumblr users, often challenging or debunking the false and incideniary claims in the IRA-linked original post. Removing those authentic posts without your consent would encroach on your free speech—and there have been enough disruptions to our conversations as it is.

What we’re doing to stop future disinformation campaigns

You’ve probably read that U.S. intelligence officials expect foreign agents to try similar propaganda campaigns in the future. We’ll be monitoring Tumblr for signs of state-sponsored disinformation campaigns, and if we see anything we will…

Terminate the accounts and remove their original posts.

Notify you if we determine that you’ve liked, reblogged, replied to, or followed a propaganda account.

Add the username to the public record.

Alert law enforcement.

There are also things you can do to help stop the spread of disinformation and propaganda.

Be aware that people want to manipulate the conversation. Knowing that disinformation and propaganda accounts are out there makes it harder for them to operate. The News Literacy Project has this handy checklist for spotting their tricks.

Be skeptical of things you read. Disinformation campaigns work because they know people don’t fact check. Look for reliable sources, and double-check that the source really says the same thing as the post. You can also check Snopes and Politifact. Both are award-winning resources and usually have the latest viral claim fact checked on the front page. 

Correct the record. When you see people spreading misinformation—even unintentionally—politely say something in a reblog or reply. If it’s your friend, send them a message to let them know.

One last note: Please vote.

Transparency won’t mean a thing if we don’t participate in the process. Whatever your political stance, voting ensures a government that represents your interests. For our U.S. users: You can register online or by mail, and many states are holding primaries right now.

The internet could change next week, and not in a good way

You may have heard about the efforts in Europe to reform copyright law. The debate has been ongoing in the European Parliament for months. If approved next week, these new regulations would require us to automatically filter and block content that you upload without meaningful consideration of your right to free expression. 

We respect the copyrights and trademarks of others, and we take all reports seriously to ensure that your creative expression is protected. We make this clear in our Community Guidelines. There’s already a legal framework that works and is fair: Today we take down posts and media that contain allegedly infringing content when we receive a valid DMCA (Digital Millennium Copyright Act) takedown request. We also provide clear-cut ways for people to fight back if they believe their removed content was not a true violation. These instances are monitored and reported and live in our biannual transparency report. 

The suggestion to use automated filters for issues of copyright is short-sighted at best and harmful at worst. Automated filters are unable to determine whether a use should be considered “fair use” under the law and are unable to determine whether a use is authorized by a license agreement. They are unable to distinguish legitimate parody, satire, or even your own personal pictures that could be matched with similar photographs that have been protected by someone else. We don’t believe that technology should replace human judgment. Tumblr is and always has been a place for creative expression, and these new regulations would only make it harder for you to express yourself with the freedom and clarity you do so now. 

If you access Tumblr from Europe and want to act, you can find more information on saveyourinternet.eu. 

Reinventing the Wheel

Planning a trip to the Moon? Mars? You’re going to need good tires…

Exploration requires mobility. And whether you’re on Earth or as far away as the Moon or Mars, you need good tires to get your vehicle from one place to another. Our decades-long work developing tires for space exploration has led to new game-changing designs and materials. Yes, we’re reinventing the wheel—here’s why.

Wheels on the Moon

Early tire designs were focused on moving hardware and astronauts across the lunar surface. The last NASA vehicle to visit the Moon was the Lunar Roving Vehicle during our Apollo missions. The vehicle used four large flexible wire mesh wheels with stiff inner frames. We used these Apollo era tires as the inspiration for new designs using newer materials and technology to better function on a lunar surface.

Up springs a new idea

During the mid-2000s, we worked with industry partner Goodyear to develop the Spring Tire, an airless compliant tire that consists of several hundred coiled steel wires woven into a flexible mesh, giving the tires the ability to support high loads while also conforming to the terrain. The Spring Tire has been proven to generate very good traction and durability in soft sand and on rocks.

Spring Tires for Mars

A little over a year after the Mars Curiosity Rover landed on Mars, engineers began to notice significant wheel damage in 2013 due to the unexpectedly harsh terrain. That’s when engineers began developing new Spring Tire prototypes to determine if they would be a new and better solution for exploration rovers on Mars.

In order for Spring Tires to go the distance on Martian terrain, new materials were required. Enter nickel titanium, a shape memory alloy with amazing capabilities that allow the tire to deform down to the axle and return to its original shape.

These tires can take a lickin’

After building the shape memory alloy tire, Glenn engineers sent it to the Jet Propulsion Laboratory’s Mars Life Test Facility. It performed impressively on the punishing track.

Why reinvent the wheel? It’s worth it.

New, high performing tires would allow lunar and Mars rovers to explore greater regions of the surface than currently possible. They conform to the terrain and do not sink as much as rigid wheels, allowing them to carry heavier payloads for the same given mass and volume. Also, because they absorb energy from impacts at moderate to high speeds, there is potential for use on crewed exploration vehicles which are expected to move at speeds significantly higher than the current Mars rovers.

Airless tires on Earth

Maybe. Recently, engineers and materials scientists have been testing a spinoff tire version that would work on cars and trucks on Earth. Stay tuned as we continue to push the boundaries on traditional concepts for exploring our world and beyond.

Why We’re Learning To Lean Out

This is a post from Denise Chan, Content Marketing Manager

We’ve been doing something new at Bitly lately. We’ve been making more of a priority to lean out as a team. We realized that, for all the talk about how startups should do more, faster, there’s a lot more value to slowing down and taking a moment to sit back and allow your long-term objectives to fall into focus.

There will always be competing opportunities that vie for our attention, but if we don’t make it our number one priority to address fundamental challenges, everything else will be done in vain. That’s why, our CEO, Mark Josephson asks the Bitly team one question every day:
