Wow...
Put it this way, if a hack has a security exploit, and a bad person finds out, if there is a list, he can very easily go to each site and attempt to exploit the loophole.
Hence why there is no list, and why the old list which we had was removed. (Members didn't want to be on the list too - they contacted to be removed, but still wanted to get hack updates).
The hack author can still see who has installed his hack, but we assume the hack author is not a bad person.
