I found this through IRC a few minutes ago, chances are it's already been passed around a bit before a public paste. Edit: It looks like that amounts to about 14.5% of all the passwords available in the accounts.csv file.
Check to see if you are on the list. Keep different passwords for everything. I did a search and did not see this posted.
There are actually people who have not changed their password yet??? I changed and my PW is not even on MTGox. come on people, this is a no brainer, CHANGE IS GOOD!!
