I am receiving 0.00000005 BTC approximately once per day without My approval

[refaelsh]

I hope it is the right forum for this question.
It started approximately a week ago.
My wallet is on blockchain.info.
Once per day approximately, I would receive 0.00000005 BTC.
I don't know who is sending, I don't know why.
It started happening all of a sudden.
Any ideas what can it be?

What is the address that is receiving these payments?

[LoweryCBS]

Probably just Hashking starting up his repayment plan again.

I don't know how to check it.
I have several addresses I used over the time but mostly I use this one:
1PhKfcoFJbgfPcCPYih1RtWJWdYkmE2p4K

I never used Hashking.

Are you sure it isn't payouts from some free BTC websites?

Yes, I am sure.
I do in fact visit many of such sites on a daily basis, but:
1. None of them pays such low amounts. I've checked.
2. This started happening a week ago. I did not visit new sites in the past month.

Ahh, OK, well, to be honest I don't know what it is, none of those addresses have tags or show up in Google, but I occasionally receive small amounts of BTC and have no clue where it comes from and I'm sure it happens to other people as well, It's only a small amount (less than $0.01) so I'm sure its safe to spend it, it's nothing to worry about.

I am not worried - in fact I am happy, its free money - but I am very curios.

That's the beauty of bitcoin. If someone wants to send money anywhere, there is nothing you can do to stop it, even if it's your wallet they're sending money to

[Stephen Gornick]

I don't know who is sending, I don't know why.

Where did you give out that address?   For instance if you registered a "change address" on Bitcoin-OTC that would be how someone got your address.

A method like this can be used to identify user accounts.
Say I send Blazr 5satoshis to his public address 1BLazrT9v82xvYFTZYn5D5zzra2gaLUQ7s. The costs for this are basically nothing. But the amount is so tiny that eventually when Blazr sends some coins, it will always be combined with other transactions, that most probably using some other address - lets say his "secret" main address. As a result his former "secret" main address is now revealed. And all this at basically no cost. Do it with most public addresses and you end up with a pretty good database.

Totally true, but, you can always go through an addresses previous transactions on blockchain.info and look for transactions that have more than 1 input address, no need to send 5 satoshi's. This also doesn't work with shared wallets.

I have a handy script that does this for me and compiles a list of addresses that the person may own, very handy for vetting possible lendee's

[veteranBtc]

Be happy, you gonna be rich

[marhjan]

Some (oddly motivated) people find it amusing to 'troll' people by sending tiny amounts of satoshis around randomly.  There were two players on the Dragon's Tale casino who would repeatedly send 666sat and various other nonsense to people to 'bother' them.  And some other players got really upset about it, I always just figured it's free money and shrugged.  So it's possible that your creation of this thread is making someone very moist right now "heh heh...  my plan is working perfectly..."

Off-topic - I approve anyone sending any amount of btc to the following address

Looks like it can all be traced back to this transaction back on Feb. 20:

Interesting...Nice find.

Question, why is the address 1JYvvL67LrSGCG77cy4rmpUXCFfSub4JkG highlighted in orange?

It indicates that it is the input that I clicked on to find where it was used as an output.  For anyone who might be curious here's the chain of transactions.  If you look at any of the transactions, it's pretty obvious that the addresses listed below are just change addresses where BTC are being sent back to the same entity that is in control of 1JYvvL67LrSGCG77cy4rmpUXCFfSub4JkG.

which is the first transaction in that chain where I see your address 1PhKfcoFJbgfPcCPYih1RtWJWdYkmE2p4K

So you are receiving those bitcoins at 1PhKfcoFJbgfPcCPYih1RtWJWdYkmE2p4K from whoever is in control of 1JYvvL67LrSGCG77cy4rmpUXCFfSub4JkG.
