If you're going to say that this signature qualifies as acceptable for
the above SSP record, then you have created a security hole that renders
SSP utterly useless.

It rather depends on my opinion of hacker.com.  I agree that
signatures from unknown domains are uninteresting, something that's
the same with or without SSP.  But if I have reason to trust
hacker.com, I'm done, I'm not going to check anything else.
