this one was before I changed REMOTE_ADDR in my scripts to HTTP_CF_CONNECTING_IP, and you can see where it thinks the visitor is from cloudflare. all the posts on my forums, all the new users, etc, were all showing from that IP address.

by making that change, I am seeing their IP, and not the cloudflare IP
