I really want the username and email the blocked IP tried to register from to be included in the PM. Actually, the way I want it to work is for a new thread to be created in a specified forum. In the first post of the thread would be the IP as well as the hostname the IP resolves to, the username and email address the IP tried to register with, and the blacklist that pegged the IP.
Subsequent registration attempts from the same IP would appear as replies in the thread and would only list the username and email the IP tried to use.
Some of this is within my abilities so if I ever get time (hahahahahaahaha) I will try to set it up myself, but I am at best a no-talent hack at this stuff. I'm not even sure I can get it to detect the name and email
