Hijacked url??? example.com/cron redirects to sedoparking.com???

why is this one 404 url redirecting to somewhere else? Its doing this on every Drupal powered site on 1and1.

updated - 1and1 finally came back with a more realistic answer. Its a direct copy paste (their lang skills are a little short):

This two URLs namely: example.com/call and example.com/cro is working fine since this two directories namely call and cro is not existing on your 1and1 webspace in which according to your .htaccess configuration specifically on your mod_rewrite, they will just be redirected on your example.com homepage. This URL now example.com/cron is not redirected on a different server page but instead it's being redirected on your 1and1 error 404 holding page. It's because your /cron folder is being adapted on your cron.php file inside your /drupal-6.12 directory which now contradicts on your .htaccess configuration specifically on your mod_rewrite part. As you can see there, if you will rename your cron.php let say to xcron.php, your example.com/cron will now display fine without any problem. So what you gonna do now, is to check your mod_rewrite directives inside your .htaccess file which is for your cron directory.
