Without a node with modified code how does one get around to doing what you're doing in an automated way?
Some kind of pseudo-node. No code from any other client.
Also, a follow up question, what are your main reasons behind this?
Are you doing this to prove a point, like with the transaction spam attacks?
Just because I am able. Isn't it funny? I have not any other reason today. But... I have some ideas for future.
Why did Satoshi invent bitcoin? I really think he had the same reason - because he was able to do it.
