Here's the reddit postToday I sent myself some Bitcoins to btc-e and then got a notification from my blockchain app that I received 0.00000001 BTC.
I looked up the transaction and address and found that it's publicly labeled "Play and Win BTC" which redirects to bitwars.org. Checked their address and they've been sending 100's if not 1,000's of minor transactions to Bitcoin addresses which send or receive payment by what looks like a blockchain transactions scan.
Transaction ExamplesGot home tonight and was going through the routine check on my site (
cryptothrift.com) when I saw the same amounts sent to disposable addresses used for people to deposit funds:

That's when I clicked to what they're attempting to do, spam the network with minor fee-less transactions to advertise their service. Which reminded me to what I read (but not confirmed) about a similar game played by bitcoin.tm on

Update: When I sent the coins to my btc-e account, I noticed that I got the same amount transacted twice. First one confirmed nicely, the 2nd is still sitting with 0 confirmations (a typical double spend attempt) and the TX ID is invalid

... again, the transaction ID
