You should be able to get away with spending quantities that don't include these satoshis, it depends on how your client builds the tx script.  You can only spend it if you generate a tx script that doesn't spend the spam outputs.

Wish I understood that tacotime.
So, should I avoid using the address thats been spammed?
I have read that deleting addresses from your wallet can cause problems- is that true...

Avoid using it until the spam has one confirmation, unless you get new spam.

If the address is otherwise unused, remove the keypair from your wallet, as it costs more to spend than it's worth anyway.  Deleting keypairs (addresses) is not consequential for well implemented software, but might be bad for poorly implemented software.

It seems once they send one spam to you, they monitor the address, and send a spam everytime.  I now have 3.

edit: My mistake, see above.  You shouldn't ever be allowed to spend these unless your client is really broken, and the 1 satoshi tx should never enter a block.

Edit: Mea culpa. This attack described by Localbtcbuyer shouldn't work because most wallets will never allow you to incorporate an unconfirmed tx originating from an address you don't own, so spending is safe unless I'm missing something.

So, I'm not totally sure where these are coming from or why, aside from simply being advertisements or spam containing messages to end users of clients.

The malleability issue is described further here: https://blog.conformal.com/transaction-malleability-no-shortcuts-allowed/

Remind me to sleep tonight because I'm clearly verging on incoherence X)

Sounds like there is a good opportunity here for somebody to develop a "spam filter" to put a stop to this. A wallet that did that would be worth having.

A problem will occur if you need to spend your entire buitcoin balance, but they sent you this 1 satoshi.  Since it wont confirm, your new transaction will not confirm either, until it is dropped from the nodes.  I almost transferred my balance elsewhere, but then I saw that I had 2 of those satoshi transactions, so i didnt send full balance.

They find addresses from blockchain.info. Most likely they look for the newest TX's and scrape addresses. Then, they spam them. It's advertising to millions of people. Think of it as viral marketing on YouTube, just this time, it's forced onto people. When you do that, people start to HATE the service.

Just had a look to see what "bitwars" is, am none the wiser.
Still don't understand how it can be affecting me if I have never had any contact with them.
Did they harvest my address from somebody else that I had contact with? Like some kind of infectious bit-disease!

Happening to everyone. It's bitwars.org... I'm getting tired of it too.

This evening I have had two deposits of 1 satoshi each appear. So far unconfirmed, seen by 1 peer.
I have put the transaction hash into blockchain.info, and they appear to be part of blocks containing hundreds of single satoshi transactions.
Is this some kind of attack on the blockchain?
I noticed that one of the addresses in one transaction contains the characters "enjoy", and in the other on "sochi".
What are the chances of real words occuring in a bitcoin address?
I could post the transaction hashes here if it is safe to do so.

Vince.
