Mine was, but the password there is more than 4 years old, I have changed it several times since then. Makes me think that this leak is just a collection of old leaks out together.
this is exactly what has happened, someone pulled together a load of data from hacks and leaks and made one file. the data in general appears to be years out of date, of course some people may still have the same password and may have reused credentials for other sites.
