Can we really call that an attack ? Probe requests were made especially for that purpose. It's more a feature than a vulnerability imho. And knowing the number of active nodes does not compromise in any way the anonymity of the people using freenet. We already know that using opennet is like yelling on every roof that you use freenet.
