What is wrong with some people? Seriously... someone with the technical skills to automate this can't think of something more worthwhile to do than to steal pennies?
Do it enough, and the pennies add up.
I started with one of the .05BTC transactions and traced it back to this coin
, donated to the bitcoin faucet:
I then followed the money given out by the faucet. The first 9 transactions haven't been redeemed yet (as I write this, approx. 2215 UTC on April 14). Then transaction #10 is this interesting fella
Ooh, look, it has 17 inputs, one of which is .04BTC and the rest are 05 BTC, and one output. So then I started following that coin. Next up was a transaction which had the .84 BTC input as #1, plus a whole bunch of other .05BTC inputs.
I didn't follow each of the .05BTC transactions to their source, but I followed enough to convince myself that each .05BTC transaction originated from the faucet.
The .84BTC transaction was combined with 13 other .05BTC transactions, which I sampled enough of to confirm they also originated from the faucet. The single output of that transaction was worth 1.49.
It's pretty clear by now that one person controls all the addresses I mentioned so far - the 30 addresses drained from the faucet, plus the .84BTC intermediate and the 1.49 BTC final.
The 1.49BTC transaction is input 1 of this transaction
Input 2 is the 50BTC bounty from this block
. Input 3
. The inputs to that transaction all appear to be payouts from a mining pool. This tells me that the person (or, probably more accurately, one of the people) who is sucking the faucet dry is also a solo miner, AND a member of a mining pool.
Seriously, dude? Mining isn't enough for you, ya also have to rip off the bitcoin faucet???
At that point, the thief started trying to cover his tracks with some laughably see-through attempts at laundering the money (side note: I am glad that I have not yet posted my ideas on anonymizing Bitcoins, as that would have made the tracking much more difficult. After this escapade, I don't know if I will.).
The above transaction has two outputs: one for .68BTC and one for 71.29BTC. At that point I thought "OK, here we go, have to follow two separate trails." Nope. The next transaction in the chain combined the two coins, with two other outputs. Again: Seriously, dude??? This is supposed to confuse someone??? A few transactions later, add in other BTC for a total value of 198.62BTC (now we're talking serious coinage!): http://blockexplorer.com/t/CWMyLvqes
Right, so the transaction has two outputs, and dude tries his obfuscation again. As I'm starting to get bored with the "click-click-click" monotony, I finally come to this transaction
which breaks the pattern. Output 1 is 188.61BTC which continues to rinse-and-repeat. Output 2, for 10.01BTC, is more interesting. It leads to this transaction
The transaction gloms together 6 different transactions worth a total of 570.957 BTC. Output 0, for 0.019BTC, has not yet been redeemed. Output 2, for 570.938, does the rinse, add in more BTC, repeat a few more times. Now, I should note that most of the 570BTC appears to be legitimately gained from mining.
So, dude who's sucking the faucet: we're on to you. It's only a matter of time until we find you and force you to refill the faucet and put you on display in the Hall Of Shame.
The mystery, though, is what the (other?) thief intends to do with the BTC that haven't been redeemed yet. Looks like he has sucked quite a bit of cash from the faucet, and hasn't redeemed it yet.
