While this is an awesome idea, I can't help but think about the humongous potential for abuse. Were the logs to be leaked, stolen or otherwise compromised, you now have a goldmine of potentially vulnerable systems. Even if the results weren't logged, you'd now have a list of systems where the sysadmin wasn't 100% sure.

So the IP/result combination is not stored, but technically the IP address and result could be stored without there being a relation between them?

Technically the answer is yes. We've deliberately made it very difficult (along with not out and out storing the data). All of this is a little academic though - If you wanted to compile a list of targets you'd just do the scans yourself... It'd be million times faster and easier than trying to hack it out of us.
