Is there a software that I can use to automatically create 0-value transactions (spam) using my own node? I have found one that uses the browser, but that one is very slow and is currently not working either (not updated?). Edit: The question is not IF/WHY spamming the network is good. I assume spamming from my own node is good for the network. The Q is HOW to do it.
If you want to use POW on your own node to speed ut other ppl's transactions, you actually only need to install NodeJS and use the js-lib. It has the same feature as the wallet currenlty have - promotion of transactions. This takes the other person's transaction-hash as parameter and will promote it as defined in the other parameters you specify...
If you need help to create a script to be run - just ask.
you can use this spammer client-side
just comment out the line 227 in transactionSpammer.js. this way the PoW is done by the full node. make sure you exclude the attachToTangle command in the --remote-limit-api configuration option of the IRI.
in theory you could also let the spammer run as a nodejs module on your server. you have to tweak the repo a bit to make this work.
