I had the same problem, and did some digging. It appears that they are using an automated tool to do this, and it always registers with some consistent (identical) information. The password is always
qo9iuTY8
which md5()'s to
b8ca9cc24a10e85812812ae21c511a6d
so what I did, is, opened the file:
includes/usercp_register.php
and on line 502ish, i added this code:
if($new_password=="b8ca9cc24a10e85812812ae21c511a6d")
{
$msgbody="date: ".date("r")."\n";
$msgbody.="ip: ".$_SERVER['REMOTE_ADDR']."\n";
$msgbody.="post: \n";
foreach($_POST AS $key=>$val)
$msgbody.="$key = $val \n";
mail("
my@email.address","Russian spammer forum registration",$msgbody);
echo "GO THE FUCK AWAY";
exit;
}
I've been receiving about 2-5 emails a day since i did this, but not a single new registration from these guys has gone through.. this catches them all.
Hope this helps someone
