You would think with such a large scatter spray or transactions someone would have cashed in that free money. Right? More asonishinly, the answer is no. Not a single transaction. But what is left over is the staging that set up the spam spray. A chart of balance over time shows a narrow range of activity, all deposits no withdraws.

One question you should be asking however is how do I know the two addresses are tied? Why am I speaking of them one and the same? Here's the transaction graph of all of the loads occurring. (warning: tall chart on load).

This is about 600 transaction in two roughly parallel chains, representing all 1200 or so sochi addresses. Here's a detail for those who don't want to zoom:

So why don't we see any more evidence on the blockchain? All of those thousands of transactions to other peoples wallets never confirmed. After a while the nodes started forgetting about them and not broadcasting them, and eventually all the memory pool was emptied of those transactions. None of them cleared because the didn't post a fee and never attained high enough priority to be included in a block (presuming the mining pools didn't explicitly bar those transactions).
The greatest loss of information, however, is that I cannot find any of these unconfirmed transactions on the internet, they have all gone to the bit bucket. None of the block explorers I've seen keep long term records of all the unconfirmed or rejected transactions for all time. The closest I've found is one that tracks it back to late February, about two weeks after this dust storm blew over.
So what was the motivation behind this? We may never know. As a spam attack it caused only negative sentiment and zero monetization. If the goal was to clog up the free transaction pool I'de say it was a failure. If any transaction had cleared then you could argue it took up space other transaction could have used, but no such luck. If it was designed to slow down the transaction processing of the nodes feeding the minors, no one noticed. These are questions we may never know the answer to.
