edit register.php, find:

PHP Code:

$DB_site->query("UPDATE user SET usergroupid=2$dotitle WHERE userid='$u'"); 


Replace it as:

PHP Code:


$ban_isp='ENTER HIS IP HERE';
$source_ip=$REMOTE_ADDR;

if (substr($source_ip, 0, strlen($ban_isp))==$ban_isp) 
{
$DB_site->query("UPDATE user SET usergroupid=X WHERE userid='$u'");
}
else
{
$DB_site->query("UPDATE user SET usergroupid=2$dotitle WHERE userid='$u'");
} 


Replace X with your new usergroup for these users.
Enter ban IP in the part ENTER HIS IP HERE
You can enter exact IP or partial IP like "195.203.150." but dont enter xxx like:
195.203.150.xxx
195.203.xxx.xxx

The correct syntaxs are:
195.203.150.200
195.203.150
195.203
etc.
Works only if you enabled email validation.
Dont know about COPPA but I guess it wouldnt matter.

Not tested, should work..

Enjoy..
