There're still a lot of points on these plots that don't make sense, though; generally they look like vertical stripes labelled as sets of small sell orders, both far below and far above the market price. User 30 has what looks like a large sell (in Mar 2013) far above the highest-ever price. So either MtGox's order-matching is way more broken than anyone ever knew (unlikely), or these actually represent fees, withdraws, or something similar, and the y-axis position is meaningless.
Also worthy of note is that massive sell order by user 1 in Nov 2013. That's hard to interpret without knowing what the dots on that graph really mean (I doubt they're trades), but it's likely significant.

>The special user TIBANNE_LIMITED_HK is not represented in the MtGox 500 since its trades are not in JPY. You can read a conjecture on the role of this user. The other special user, THK, shows up as #1 in the MtGox 500.
"Bots" offer a lot of stability to the market because they don't react to bad news. Though an error can cause "flash crashes" As happened in May of 2010 on the stock market.
Could one of these graphs represent the activity of Willy?
As an aside, I experienced a nice bit of schadenfreude when looking at a lot of the graphs from ~250 to ~299
My favorite is 117. They are the Devon Sawa in Final Destination of Bitcoin.
The amount of money lost is a little easier to get your head around when you see so many traders buying at relatively high prices towards the end.
I’m even more puzzled by the rates out of trade: did MtGox allowed traders to agree one-on-one on their own rates? That would allow a lot more laundering than any theft.
Missing too are relative size of the traders.
This is actually rather scary. Enough people have logged data that these can be dereferenced despite the feeble attempt at depersonalization, but I guess the names will come out in the legal proceedings anyway, depending on jurisdiction.
Then we'll have Newsweek writers at our houses asking how we feel about "losing millions" when our cost basis was really around $10. :-)
To head that off: "Umm, now I don't have to worry about how to declare this on my taxes? 'Miscellaneous Income' was making me nervous."
I think you're maybe looking for bowlderization or anonymization or something similar?
Anonymize is probably fine, but I want "reversible anonymization". :)
