Well I figured it out, I managed to fix my emailer, so now I have it set to where they have to enter a valid email to sign up, now i cna just block the email addresses they come up with.
I know when I installed this that it highly recommends not using front page, but alas that is my editor. I had to reset my FP extensions a while back and when I did it broke the connection to the database.
After posting my plea for help I went in with my Front Page went to TOOLS>WEB SETTINGS>DATABASES>VERIFY and wal-la!! It now works!
SO now the little trouble maker has to put in a valid email to sign up and click on the verify link from the email the database sends em and I can block the email addresses and I won't have to deal with the ever changing IP addresses!
There's more than one way to skin a cat!
I was determined this person was not gonna beat me! 
Thank you everyone for your help and suggestions!!
