See the link above smartbtc is sending payments worth 0$ and its irritating me to see that. Any way to disable payments from them?

There is no way to do that. The protocol is currently not equipped to reject legitimate transactions (malicious as the intent may be) to valid addresses. For now, you can try to minimize the effect of dust spam on your input list by using a new address per transaction.

It is not possible to disable receiving payments from a particular address (even if you could they could easily send from another address). The transactions are not actually worth nothing, but they are worth very little.

I do agree that they are very annoying and will likely never be spent. I believe there is a program that will allow you to essentially donate these inputs to the miners via a transaction with no outputs.

I have not received any incoming spam transaction but it could be a problem expecially if it will be done by many more companies/users.

I don't think that will help. In fact, you're likely just to recieve more spam. Some people have reported being sent payments to every address they've previously used even if only once. Some users got a decent amount from one site that was sending out 0.001 payments. 

Hey if these companies want to pay transaction fees, why not?

Very true...its their loss rite

These transactions is 2.6k in size and paid only 0.0001 btc fee. I do not think they will be confirmed. Wait a few days, they should be removed from the transaction pool. If they do confirm, pay 0.00010001 as fee next time you send coins and you can get rid of them.

So, if you want to, you can send 50 transactions to someones account, with 1 satoshi and no fees?

How does the dust influence the other persons account?

Sorry for bad questions.

It's possible but the one i received was with 0.0001 fee. But wherever you wants to send coins from your blockchain wallet it will give an
unconfirmed output error saying "Some funds are pending confirmation and cannot be spent yet (Value 0.00000001 BTC)".
So, its just another dust transaction in your wallet that may or may not gets confirmed.

I think I received one too.

It is free money anyway.. If we reach moon, might be some significant money.

Just ignore or use other addresses.

Yes but I don't think they will ever confirm and get sent back to the sender hence why they're spam.

Yeah im getting these spammy transactions as well, and i cant find a way to block them.

They should add a way to avoid transactions under a certain value (say 0.00001 or so) so you don't get spammed. Im getting spammed a lot often for some reason. Who is the no lifer doing this? lol.

As others said, there is no way to block such dust transactions and these transactions will be dropped in a few days after getting no confirmations.

On bitcoin core, you won't be able to spend the unconfirmed outputs by default.
So, having some unconfirmed dust transactions to your addresses won't affect you.

I am not sure about how other wallet clients handle unconfirmed outputs though.

There is a dust output threshold in placed, to make such transactions less likely to get included in a block. But AFAIK, it doesn't prevent the transactions from relaying across the network.

The persons creating these transactions are most likely trying to that BtcSmart site which obviously is a ponzi.
