[How to delete my account after a hack]

My account information was stolen after the hack https://forums.phpfreaks.com/topic/298874-alert-the-phpfreaks-forum-members-data-appears-to-have-been-stolen/

 

But it appears there is no way to delete my account now? I don't want to be a member of this group anymore. How do I delete my account?

[Hashing Method Feedback Wanted]

I did some research on hashing, and it looks like both md5() and sha1() can be reversed, given enough time and processing power. I wrote a function that (I think) would make it considerably more difficult to unhash a value. Do you think this is overkill? Are there any problems that jump out at you? Here is the code:

 

<?php
function hyper_hash($value) {
    for ($i = 0; $i < 100; $i++) {
        if ($i %2 == 0) {
            $value = sha1($value);
        }
        else if ($i %3 == 1) {
            $value = base64_encode($value);
        }
        else {
            $value = md5($value);
        }
    }
    return $value;
}

$initial = microtime(true);
echo "\"12345\" hashed to: " . hyper_hash("12345"). "<br /><br />";
$final = microtime(true);
$delta = $final - $initial;
echo "Time taken: " . $delta . " s";

?>

Here's a page with this code running: [removed]

 

Thanks for the feedback,
