Has anyone else been the recipient of unexpected subcent transactions?  I've received some very small (<0.000001) transactions in the last few days.  They weren't from myself and I wasn't expecting them.  Browsing the block chain, I see other address receiving such transactions as well.  I find this very odd, as they are paying more in tx fee than the transaction itself.  Is this some sort of probing attack, or is it just a misbehaving client?  I hope nothing nefarious is happening.  Does the client handle receiving transactions for yourself differently than other transactions?  Is there any info leak here?  I could see someone trying to probe clients with transactions to get info on which client owns what and then go into attack mode when a suitable target is found.

Here are a few examples of some blocks I noticed with these small transactions.  The destination addresses seem to be used, so I don't think these are the change address.  There are many more than these.
block 132736 has an output for 0.0000001
block 132738 has an output for 0.00000001
block 132751 has an output for 0.00000005
block 133374 has 3 outputs for 0.00000001
block 133431 has 2 outputs for 0.00000001

If anyone knows what's happening here, I'd be interested in the explanation.

No, not specifically my address.  Although after I posted this someone did send a small amount there.  If you look at the blocks in the first post there are other addresses with previous activity that have had very small amounts sent to them recently.

I haven't (at least not yet); could these 'coins be tainted somehow (like being bought with stolen credit cards) and this be an attempt to attack Bitcoin by trying to get people to be forced to give up their money due to suspicion of being involved in criminal activity? (in Second Life, there have been some instances of such attacks, people donated stolen money to their target and then LL charged treble damages of the victim, somtimes even resulting in negative balances and loss of data)

(I dont always get new reply notifications, pls send a pm when you think it has happened)

Wanna gimme some BTC for any or no reason? 1FmvtS66LFh6ycrXDwKRQTexGJw4UWiqDX Smiley

The more you believe in Bitcoin, and the more you show you do to other people, the faster the real value will soar!
