TypeKey has entered the ICU. The popular support for TypeKey hinged upon the social capital of Ben and Mena Trott. Between the capital drawdown of the MT 3.0 crisis and reports that spammers are already TypeKey registered, it badly needs life support. I’m not shedding any tears. I think that TypeKey is overkill for the spam problem and that PageRank Stripping is a better solution.

I don’t understand why people think comment links should be rank full. But given that they do, it seems to me that the answer is link moderation. Comment moderation stifles the conversation by introducing lag. Link moderation would allow comments to appear immediately, but links would be rank stripped until explicitly approved. A rank full whitelist could be added to alleviate the moderation burden.
