I checked and the site is still up but I think someone either hacked or bought the heRO redirect link :
http://www.gamesites200.com/ragnarok/out.php?id=11137 <-- this leads to an odd site
but the
http://www.gamesites200.com/ragnarok/ is still up... o.O
EDIT: clicked a few others servers and they all get redirected so it's not just heRO... sneaky and evil.
