Sadly, it also seems like I have to have a policy for syndication, since there are now over a dozen sites re-publishing my complete RSS/Atom feed for purposes that are not entirely in accordance with the Creative Commons Attribution-NonCommercial-NoDerivs 3.0 license.
So I am henceforth asking for people to at least ask me permission to do so, and reserve the right to automatically tag such sites with dire warnings and random junk inserted into my feed (I am now able to do that with a fair degree of accuracy and randomness to prevent feed parsing and other tricks).
If necessary, I will change the licensing policy completely to prevent this sort of re-use of my content for borderline commercial purposes.
(Another option that has been suggested to me involves adding advertisements to my RSS feeds, which I have so far been generally opposed to. But my view on the matter has changed over the years, so my guess is that it is only a matter of time.)
