more comment spam

I need to find an updated version of HashCash soon. In the meantime, I turned on a bunch of bristly comment-spam-unfriendly options, such as “you must be registered to comment”. UPDATE: Some evidence exists that HashCash has been worked around by some comment spammers. So I guess it’s time to roll my own bad idea that won’t have enough penetration for spammers to bother.

I’m thinking about some kind of crazy XML-RPC handshaking.
