FWIW, as the person who has been doing the initial implementation, I can tell you that we currently only have a whitelist. I can appreciate why the person who was editing the FAQ for the website put in the world "blacklist" as it makes the sentence flow really well, but I agree with you about the issues (and there are also problems doing the distributed hashtable search to find nodes that don't have some property rather than ones that do have some property). I will poke about this to see if I can get it changed ASAP!
