Blocking the user from hell from accessing Dolphin

Does anyone know what ways there are to block a specific user from accessing my Dolphin site?

I have one user that is really really the user from hell and all my attempts to block him have been unsuccessful. I have tried the ISP Block but even though he logs in from the same  ISP, it lets him in. I have tried suspending him, but he then deletes his account and creates a new one. Any good suggestions on how to block this devil from assessing the site?  Thanks.

P.S. What I'd like to do is block his entire country as there may only be one or two users from his country that havent logged in in a long time. Is an entire country block possible?

It's all done through your .htaccess file.

backup your htaccess file....then add this to your htaccess file

order allow,deny

deny from 192.168.

allow from all

however change the ip numbers to numbers matching his....what the above code will do is block all ip's starting w 192.168.  so from 192.168.0.0 - 192.168.999.999 would not have access to your site...again make the numbers match the users beginning ip...or the ip range of his country.....

also using your htaccess file you can deny his ISP w this code

order allow,deny

deny from hell-isp.com

allow from all

hope this helps and good luck

192.168.255.255...

Email adress blocking? But it gaves no mod for it..

if i were u i would just block the ip range that he is using.....no use in blocking emails...as they are so easy to create new ones...using yahoo or something like that.....

again...put the first 2 sets of numbers...like 192.168.   and leave the rest blank so that it will block all ip's beginning in those numbers....
