I can confirm the same thing happening to me. The originating address is 1Bhv6XjXBvraivcATHwwLMscZ5xJm9FsPn and the transaction number is https://blockchain.info/tx/84d24e09adb61f6c95ca57338ac8bc548d61b7efa56f593aa581c633112cd886 for 0.00000001 BTC.

Anyone else able to figure what is going on here?

What possible purpose is there for almost 500 transactions sending that amount to ~50 times per txn?

It might be the NSA using some new form of hacking to locate Bitcoin addresses in a way we haven't thought of yet.

Whatever you do, don't tell them about the block chain. They will locate a lot of Bitcoin addresses in that thing!

Does receiving a satoshi to your address trigger any p2p response from the client?
