Very weird activity in my wallet

[Foamy]

I checked my wallet today and it said I had 2 satoshi uncofirmed. So I checked the history and there were 2 incoming transactions for 1 satoshi each that were hours old and unconfirmed. What is weirder is when I checked the address I received the bitcoin with it was not in my receive addresses. It must be part of the keypool.

This is the address.

I hopped on blockchain.info and tracked who sent me the 1 satoshi tx's and its one address sending to thousands of "random?" addresses. Always 1 satoshi.

Could this be someone attempting to map a bunch of addresses or something more nefarious?

Here is the blockchain.info link to the address that sent me the 2 tx's.

and another one that was part of the same group of transactions.

Can anyone explain this odd behavior?

Could the vanity addresses mean something? lol

I also just found this. It looks like its happening to alot of people.

I think it's well-explained in the reddit post and the referred topics.

Don't spend from that address until the transaction is rolled back. And if it's not rolled back and you can't make use of Dust-B-Gone, send the entire content of the tainted address through a mixer or through a newly-generated address on an exchange, and then re-generate the exchange's receiving address once again.

That's my understanding of the future actions.

An interesting observation: I got spammed from only the Enjoy address against one of my addresses which was solely used on Eligius pool.

In my case it was (of course) the change address in a transaction I spent using a p2pool payment address and an emc payment address.

But the article doesn't make sense about tracking people.

Yes until I spend my own change, there is a (very small) doubt that the change address of my transaction was indeed in my wallet and if I spend any of the 1 Satoshis that transaction may confirm it - but that's no different to saying that spending my own change will confirm it's my change ... and ... do people NOT spend their own change?
Anything you do to protect your identity when spending the change you can simply add the 1 Satoshi to it also.
So, yeah I don't see the issue mentioned in the reddit article about

...
presumably in an attempt to more easily map the transaction graph (i.e., remove anonymity from the transactions)
...

It's them aliens, everyone who received 1 satoshi is going to be abducted and be anal probed.

These transactions never confirm.  Does that mean they are fake?
