Thank you for the legal warning.  To be clear, I am not suggesting a
program to examine packets and do some sort of incredible image
processing to figure out if a photograph is child pornography, or
anything that would involve packet sniffing, I just want to block
certain IPs and hostnames.  I'm not sure why this would be illegal,
since many ISPs and firewall software already do this, but I'll make
sure to do my research before I do anything, if I do anything.

I do not save logs except occasionally for debugging purposes, and
even then, they are scrubbed.  While unscrubbed logs might be
useful to law enforcement in some circumstances, I recognise that
I cannot help them catch bad people without also damaging the
privacy of good people.  Nor do I sniff packets.
