I just switched Hzzah.com‘s Apache configuration to use this line for logging:
CustomLog /srv/hzzah/log/access.log "0.0.0.0 %l %u %t \"%r\" %>s %b"
No more IP addresses logged! Only if you cause an error (404 or 500) will your IP address be logged.
I should mention that hzzah’s primary goal is for me to have fun with Django, not privacy. So while I’ll definitely warn you if I make any changes, right now its not a top priority to pursue extreme privacy.
