I found the same link too. The 1933ph..... could be DPR's address but I think the evidence is not strong enough. It's possible that he just spent 2000BTC with the tx afeecd8e47d6c3912d6c2e5f7a2ceafdecc9d4ad221480fe90847c23f81c8892.
BTW, someone sent 2 x 1.73632986BTC to 1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a on 2013-10-09.
You can verify that the first ever transaction to 1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a came from DPR's address:
http://blockchain.info/tx/70d46f768b73e50440e41977eb13ab25826137a8d34486958c7d55c5931c6081Notice that all the inputs came from this address:
15TEAwEMxVS3BK718HhwgJg7nxwyJ2ib9y. I'm pretty sure if you go backwards you can land at DPR's other addresses.
Also, I don't think DPR just spent it (to someone elses address) as the trail has only addresses that were used for mixing... all the intermediate addresses have exactly 2 transactions... 1 receive
from previous mixing address and 1 to the
next mixing address all the way to its destination
1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a.
The script I wrote followed a path that had addresses with only 2-10 transactions.
So lets break in down:
DPR's known address: 1LDNLreKJ6GawBHPgB5yfVLBERi8g3SbQS
Tumbler's receive address: 1BG9jDV3pA1MsJUnvRyWuA2b7PfGd4MZaw (only 2 transactions)
Tumbler's next mixer address: 12h6TzwPNBvDnppbsqpyXwW4oo5UUKaKSa (only 2 transactions)
Tumbler's next mixer address: 1EG9HJG9aGqzgGujfNQMiNbyqpKnFxafvE (4 transactions but note that the only output is to 1AHki5AbZYiz4fHkGSTVKN3T1Tv5PwZpnh... the remaining transactions are just too small -> this address may have been reused by the tumbler)
Tumbler's next mixer address: 1AHki5AbZYiz4fHkGSTVKN3T1Tv5PwZpnh (only 2 transactions)
Tumbler's final mixer address: 15TEAwEMxVS3BK718HhwgJg7nxwyJ2ib9y (7 transactions -> Note that this has only one output)
Final Destination address: 1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a
There is no other path followed by the tumbler. So possibly the service used by DPR was pretty weak or probably he just manually mixed it himself.
