Maybe something to consider...
Isn't there also the possibility of this scenario for dynamic IP?
-Att.net user spams in forum and admin blocks by IP address
-Att.net spammer's IP address changes after 24 hours
-Existing legit HHOF member on Att.net renews his IP address from DHCP and receives the spammer's IP address thus being blocked.
Or is the logic for example: (UserIPAddress && UserName)
I know the possibility is very minimal, but I would hate to be blocked inadvertently. Spammers should be burned at the stake! :mad:
ReCaptcha to end your spammers ability to register
One of the GREAT ways to end the forum spammers dead in their tracks is to custom modify your registration page. Most of the spammers are pre-packaged spambot programs. They target the registration page then post like mad. If your registration page is different than the norm, the spambots have no way to get in.
I did this to my forum and have been spam free ever since.
It takes a little coding to do it, but is well worth the time.
Try ReCapcha for the captcha image. It's very secure and easy to code into an existing registration page.
Plus, every time a user uses it, they are helping digitalize words in old books and newspapers that OCR programs (like the spambots use to hack your existing captcha) cannot figure out.

It took me about 15 minutes to code it in.
