BUT they seem to have blacklisted the whole list from mtgox. I tried bulks of 10 from around the list, and they are all listed as "hacked"
That's the point of that url - they combined a bunch of lists of leaked account details - if your email is associated with any of them it tells you. Technically it's "has a hash of my password from a site been released publicly" it doesn't care whether the hash has been cracked or not, and rightly so.
