| CLRG's Cheating Scandal | 2022-10-04 | clrg |
$SPOUSE just stumbled across a PowerPoint file with a bunch of text messages, pretty clearly illustrating a massive cheating scandal.
I won't post a link to the file, I won't post any screen shots, and I won't reveal any names, because I'm not interested in doxxing people.
Summary
The PowerPoint file consists of text messages between someone who I will call Sam and a number of CLRG school owners and adjudicators. Sam's messages illustrate what appears to be a years-long, maybe decades-long, racket in which adjudicators trade favors in exchange for inflated scores of chosen dancers. These favors are either reciprocal, or, in one case, sexual. I see weak evidence of money changing hands.
In addition, it is made clear that a school owner is having an extramarital affair with Sam.
Technical Analysis
The PowerPoint document going around appears to be a series of screen shots from the phone of an adjudicator who I will refer to as Sam. Sam appears to have gone back through chat history, taken a bunch of screen shots, and emailed them to someone whose name I don't recognize. The text of two emails is included in the document before the screen shots which must have been attachments.
The icons at the top of the screen shots indicate that Sam has an Android phone. Android allows you to take screen shots by pressing the power button and the volume down button at the same time. It's common for people to hit the volume button before power, which results in the phone turning the volume down just before the screen shot is taken. You can see evidence of this: the volume control appears in some of the screen shots. Someone more familiar with mobile phones could tell you the Android version and phone manufacturer.
The screen shots are of text messages with WhatsApp and Instagram (thanks to my daughter for figuring this one out). In both apps, Sam is writing the text on the right side of the screen, and the person Sam is chatting with is on the left side. That person's name and their profile icon (usually a photo of their head) can be found at the top of the screen.
The icons make it fairly clear that these messages all came from one phone. The main apps I see are Twitter, Spotify, something that's just a dot, and another thing I don't recognize that looks sort of like a stylized four-leafed clover.
There isn't really too much more to analyze here, from a technical standpoint.
My Take
I feel compelled to highlight a few observations:
Sam is a man
Due to the sexual messages, specifically one where Sam is called a "good boy", and other clues leading us to Sam's real identity, my team feels confident that Sam is a man.
Sam might be creeping on kids
There's a weird message, from Sam, saying "178 is hot". There's no additional context here, other than that 178 is a U11 girl, which means she is 11 years old or younger.
It's possible this was just poor phrasing and "178 is on fire" would have been better.
Sam is involved in an affair
In the most memorable part of the document, one school owner and Sam exchange messages outlining an extramarital affair. It's not clear whether the school owner's spouse is aware of this. But it is clear that the school owner likes Sam to have his "ass up".
Sam didn't intend for this to become widespread
While I don't know what his motivation was for taking and sending these screen shots, I feel sorry for this person. Nothing in this document makes it look like Sam was trying to publicize what was going on. And there are a few things that Sam surely regrets sending, such as the affair.
In fact, there are enough clues in these messages that my team is confident they know Sam's real name. If we're right, Sam definitely would not want any of this to become public.
This is old
The earliest message is from July 2016.
This is deep
In an exchange on slide 5, 6 of the 14 judges at All-Irelands 2019 are implicated as colluding.
In an exchange on slide 3, it is implied that up to 5 adjudicators are not part of the racket, or are at least not bribeable by the person who refers to them as "the panel from hell". Let's be optimistic and assume that all 5 of these adjudicators are not bribeable.
Taking both of these together, we can guess that 6 to 9 of the adjudicators at All Irelands 2019 were in on this racket.
There's a lot of math to get into here: accounting for how the overall rankings are computed may make it possible for two colluding adjudicators (16% chance) to compromise the entire ranking. But starting out with half the judges compromised belies severe problems, no matter how you slice it.
This probably isn't as effective as you might think
Most of these messages are just lists of numbers. One smart cheater sent a photograph, which would be easier to remember. The reality is likely that they don't remember all the numbers with 100% accuracy. This would result either in fair judging, or throwing points at the wrong number.
The younger dancers would have the most inaccuracy in cheating. For the older competitors, the accuracy of cheating goes up, as the adjudicators grow to recognize dancers.
Another thing that helps fairness is the number of adjudicators. At smaller events, there are 3 on a panel, so about a 5% chance that everybody is compromised, if half the judges are bad. This is why there are more adjudicators at the higher-placing events.
This could be detected
If anybody ever bothered to do analysis of the scores handed out, it would be pretty easy to detect the type of cheating that this document seems to illustrate. That wouldn't stop the cheating, but it would make it harder.
Unfortunately, I don't believe any of the software in use does anything like this. And I don't think the data is made available in a way that would make independent audits feasible.
The data exists to be analyzed and audited, but until there's a lot of pressure to do this, I don't see it happening. And as angry as everyone is about things, I doubt the result will be auditable data. Doing audits is expensive, and the people with lots of money have more incentives to use that money to bribe adjudicators.
These messages are just the tip of the iceberg
Let's do some arithmetic!
Including Sam, there are 14 people implicated by this document.
We are just reading Sam's messages: presumably everyone involved is messaging
everyone else as well. Mathematicians call this a "complete graph". That means
there are (14*13)/2 = 91 conversations. Put another way, we are only seeing 15%
of the racket within this group of 14 people
But these appear to mostly be UK people. If this racket is larger than the UK, you can expect much, much more has been going on that we have yet to learn about. And you can bet that it's larger than the UK: it is difficult to envsion how something like this could stay that regional, with an organization as international as CLRG.
This doesn't mean your school is involved. But it probably does mean your school has been affected.
Background
CLRG and Competitive Irish Dance
An Coimisiún le Rincí Gaelacha (CLRG) is the largest competitive Irish Dance organization in the world. Their main activity, as far as I know, is running competitions, called "Feisanna", which Americans pronounce like "feshes", because we can't read Gaelic.
These events are adjudicated by certified judges, most of whom also own dance schools of their own. These judges fly out to the events, sit through 8-12 hours of mostly children dancing around on a stage, try to write helpful notes in just a few seconds, assign a score, and then move on to the next round.
Periodically, the scores are tabulated by volunteers (mostly dads, from my experience), entered into one of a handful of online systems just for Irish Dance competitions, and awards are presented based on results computed by the systems. (None of these systems have auditable source code, to my knowledge, but that's a topic for another article.)
About Me
I'm a computer security researcher and educator, specializing in forensic investigation. That means I show up after the bad thing has happened, and build a story about what happened based on gathered evidence. The analysis I'm doing here isn't particularly difficult: my teenage daughter actually helped me put it together. But I am coming at this from a history of doing similar things.
My daughter does competitive Irish Dance with CLRG. She's been dancing for over 12 years now. My involvement has mostly stayed peripheral: running sound and electrical at events, helping with tabulation, and driving everybody home while they sleep.
I am not a journalist. I'm really looking forward to reading what gets written about this by somebody who does investigative journalism for a living. But that article isn't out yet, so I wrote this one.
