Twitter Bug Makes Tweet Archives Unreliable For eDiscovery

Tweets from 2010 and earlier suffer from URL redirection problem.


Old Tweets: Now You See Them, Now You Don’t

I’ve been on Twitter continuously since 2008-10-30. Here’s my first Tweet:

At first, I played Twitter’s game: followed lots of people, had lots of people follow me, and posted lots of Tweets. I then gained “authority” based on sites that claim to measure such things (screenshot from 2009-06-09):


In early 2014, I changed my thinking about Twitter and other social networks. I adopted document retention policies that included deleting old stuff (including email and social networking stuff) and keeping only the good stuff. Turns out that most of what I posted on Twitter was not worth the paper it was printed on, so to speak. So I deleted most of my old Tweets (and other stuff).

At some point, however, I noticed that Twitter was pretending that my first Tweet was from 2010-09-05, nearly two years after I joined Twitter:

In other words, Twitter was preventing me (blocking me?) from accessing about two years worth of Tweets. I tried finding my old Tweets on the Twitter website, via third-party apps that use Twitter’s API (such as, and via Twitter’s own downloadable archive of my Tweets. Same results: my Tweets from 2008 and 2009 were gone.

Why A Buggy (But Free) Twitter Is Problematic

This is a huge issue for several reasons.

First, it speaks to how bad Twitter’s software and customer service are. Numerous requests, both private and public (including case no. 03195672 and requests dated 2014-06-25, 2014-07-11, and 2014-11-10) to fix this problem were ignored.

Second, it means that Twitter is saying one thing (i.e. you can download all of your Tweets) but doing another (i.e. except for those which you cannot).

Third, anything you say can, and will, be used against you in a court of law. So if you are involved in eDiscovery and are either trying to delete or discover old Tweets, then you will run head first into this bug.

Needless to say, I think that Twitter should fix this issue, explain why it happened, apologize, and explain how it will not happen again. I am doubtful, however, that this will actually happen, since those of us who use the Twitter service for free are not the customers – we are the product. So we’re getting all of the customer support that we’ve paid for.

All of this reminds me of the the Jul/Aug 2002 MIT Technology Review cover story entitled “Why Software Is So Bad” ( In short, software is bad because we, as users, put up with bad software. I have complained about bad software and sloppy programming in the past (see “related posts” below). And, in some cases I’ve received a free t-shirt for my efforts. But this Twitter bug, IMHO, takes the cake.

My Own eDiscovery Discovers Twitter’s Reproducible Bug

Since Twitter chose to ignore my support requests, I set out to solve the problem myself. Here’s what I discovered.

On 2010-10-13, Twitter announced that 100% of its users had access to the “new Twitter,” including a makeover of Twitter’s web UI (

Approximately in the fall of 2014, during the rollout of the “new Twitter,” Twitter changed the format for its status URLs (Tweets) so that the sequential number at the end of each Tweet (the Tweet ID) changed length. Between 2008-10-30 (when I joined Twitter) to 2014-11-17 (today), the length of the Tweet ID doubled from nine digits (which supports up to one billion (1,000,000,000) unique Tweets) to 18 digits (which supports up to one quintillion (or a billion billion; 1,000,000,000,000,000,000) Tweets. More on this below.

On 2012-12-19, Twitter announced that users could export archives of their Tweets ( The tweets.csv file that is included with your Twitter archive contains the following nine fields:

  1. tweet_id
  2. in_reply_to_status_id
  3. in_reply_to_user_id
  4. timestamp
  5. source
  6. text
  7. retweeted_status_id
  8. retweeted_status_user_id
  9. retweeted_status_timestamp

Of these, tweet_id is the most interesting, as it contains the (presumably sequential) number needed to recreate your status URL (AKA Tweet).

I first requested my archived Tweets 2013-09-16, and it is my archive from this date that provided the information needed to crack the code on this bug. Archives requested since this one exclude Tweets from 2008 and 2009.

Of course, my old Tweets are not really gone. If you have the URL, you can still find them. Right? Or wrong?

Right and wrong.

For many of my old Tweets, the old URLs still worked. But for a few, the URL for my Tweet redirected to somebody else’s account with the same Tweet ID! Same Tweet ID, different Twitter account. Here is the proof: video, screen shots, and URLs. In all three cases, my URL redirects to somebody else’s Twitter account.

* 2014-11-17 Twitter eDiscovery Redirect Bug (60 sec)

Compare one bogus URL, which (correctly) goes to Twitter’s 404 page: (16 digits)

to three valid URLs, which (incorrectly) get redirected to accounts other than the original:

Redirected Tweet #1 from 2010-11-22


my Tweet: (16 digits)
not mine:

Redirected Tweet #2 from 2010-11-25


my Tweet: (16 digits)
not mine:

Redirected Tweet #3 from 2010-12-24


my Tweet: (17 digits)
not mine:

Why Users Should Demand A Less Buggy (And More Responsive) Twitter

Here is my tweets.csv file from 2009-09-16, showing three valid Tweets (highlighted in green) and three redirected Tweets (highlighted in yellow):


So what happened to the redirected Tweets from my account? Are Tweets from other Twitter accounts redirecting to my account? What if one of those hidden/redirected Tweets is the key piece of evidence needed in a civil or criminal trial? Litigators and litigants who think that they can rely on Twitter’s Tweet archives to make or break their case will be disappointed at the news that this Twitter bug makes Tweet archives unreliable for eDiscovery. Among other things.

This is, admittedly, a small sample size. But consider that I deleted all but eight of my Tweets from 2010. Now it’s a big problem, since three of my remaining eight Tweets (37.5%) suffer from this bug.

How many of your Tweets are being misdirected to somebody else’s Twitter account?

How many of others’ Tweets are being misdirected to your Twitter account?

How many of your Tweets are missing and inaccessible?

When was the last time you downloaded and validated your Twitter archive?

In the end, Twitter itself doesn’t really matter. Unless you really need it. In which case it matters immensely. So my advice is this: don’t use Twitter unless and until Twitter can prove that it has fixed this fundamental flaw. Just say no to bad software.

Oh and Twitter, if you’re reading this, I wear an XL t-shirt.

Sports Authority Sucks

Your brand is your brand.

My dad bought me a nice Red Sox jacket from Sports Authority for my birthday. (Thanks, Dad!) He bought the right size, but the jacket runs large (actually, “runs huge” would be a better description) and did not fit.

Since sizing was clearly an issue with this jacket, it made sense for me to go to the store to exchange it. I planned to try on a replacement jacket and return home happy. So, after lunch today, I drove to the nearest store, which was inconveniently located 25 minutes away in Marlboro.

Bad news. Not only does the Sports Authority in Marlboro not carry this particular jacket, they also do not accept returns in store for items purchased online.


In 2012, it is reasonable to assume that if a customer buys a product from BRAND-X, then the customer can return the product to BRAND-X, online or in person. I have returned items to brick-and-mortar stores that were purchased online from L.L.Bean, Sears, and even KMart.

What was I supposed to do? Mail the product back to Kentucky, have it credited back to my dad’s credit card, buy the replacement coat from the store in Marlboro, and send my dad the bill? Is this the “user experience” that Sports Authority envisioned?

I asked to speak to a manager, and the person I was speaking with told me that she was the manager. I explained that “Sports Authority is Sports Authority” and that their policy was a bad one. Heck, they could have mailed the box back themselves, given me a store credit, and let me get a replacement coat. We’d all be even, and my dad wouldn’t have to do anything. But no. The manager offered no solutions, only excuses.

I left my box at the customer service desk and briefly walked around the Red Sox section looking for a replacement jacket. Then the easy solution dawned on me: Return the jacket to Kentucky, buy a new jacket elsewhere, and never shop at Sports Authority again! Yes, that’s satisfying.

This is a not a new problem. My law school classmate Jill Smith blogged about this exact same issue three years ago when she tried (and failed) to return a $1.75 spool of thread, which she had purchased online from Jo-Ann Fabric, to her local Jo-Ann store:

Let me explain something as clearly as I can to the people who make decisions that create these kinds of conversations:

Your brand is your brand.

If you want to benefit from a brand name that has customer loyalty attached to it, you have to be prepared for your customers to view that brand as a whole entity – online and off. Your customers neither know nor care about your corporate structure. Beyond that, when a customer is faced with an employee (your corporate spokesperson, like it or not) explaining that their broken item must be mailed back to the online entity for the approximate replacement cost of the item itself, it makes your customers… unhappy. And that unhappy experience creates a very strong impression. Call it a brand association.

As a result, I now associate the entire Jo-Ann Fabric brand with dingy, disorganized stores, unhelpful employees in dirty uniforms, and a corporate policy that is a paragon of customer-unfriendly ‘gotcha’ rules.

Congratulations, Jo-Ann Fabric branding team. That’s a clear picture of a store I won’t shop at again.

This issue of proper sizing for online stores is also not new. Last month, bragged about hiring three women to do nothing but try on size 8 shoes for its online reviews. Seriously, it took Amazon until 2012 to do this?, the online shoe store for women that I co-founded, has been doing this since it was founded in 2007.

Returns are part of retail. Just like credit cards. In fact, when I purchase any product or service, I expect to be able to pay with check, credit card, or PayPal. It’s for these reasons that my law firm, Clock Tower Law Group, accepts these three forms of payment.

It just makes sense.

You know what does not make sense? Not being able to return something at Sports Authority that was purchased at Sports Authority.

Your brand is your brand.
