I did an isp ban on mine for a special member (or ex member) In global php.
PHP Code:
$ipaddress=getenv("REMOTE_ADDR");
$ip =@gethostbyaddr($ipaddress);
if (stristr("$ip", "dialup.renocs.nvbell.net")) {
print ("Sorry but but you can not view this site. Feel free to email admin@sitename if you feel you reached this in error. ");
mail("admin@sanguinox.com", "Banned user", "$ip tried to view the forum and failed");
exit;
}
dialup.renocs.nvbell.net being the banned isp
I just tosed that in top of global (I got part of it from a hack in here someplace so I take no credit for it. I added the mail to (I like to know they trying) Call me odd.
