Is there any reliable way of estimating the number of spammer controlled miners? I was thinking about the common wisdom that BitCoin should have been implemented with a hashing mechanism that is resistant to distributed processing (i.e. scrypt) and I have my doubts.
The first thing I thought when I saw a headline about BitCoin I rolled my eyes, it looked like a spammer's dream come true. But the recent protocol breakage and the (successful) coordinated effort to fix it, some I saw some comments attributing it to the concentration of miners. I also know a pooled miner that griped about an obvious hacker that he banned form his pool because the clients were doing way too much network traffic for too little work.
So, I am looking for a way to track this. The IP's stored in the Blockchain are of the first IP's that saw the coin and the payouts would go to a centralized wallet.
