I found out about this pool when asking in another thread about setting up an extra S3 to solo mine. I like to very easy to use solo mining option that your pool provides.
When you say that
0.5% goes to 1PKN98VN2z5gwSGZvGKS2bj8aADZBkyhkZ to operate the pool and contribute to further ckpool code development.
doesn't that mean that a person could track the block to your pool based on the fee transaction to PKN98VN2z5gwSGZvGKS2bj8aADZBkyhkZ?
Or is the fee address generated when a block is found to provide another layer to anonymity?
