Cheers! When I was thinking about this originally I thought you could build it as a social network. Rather than curate the internet for yourself, you could work with others to aggregate different curated views. By following only some people and having the ability to unfollow them, you would be able to keep away from spammers. Furthermore, you might be able to fork other people's curations so that people who "sell out" and include spammers can be cut out of the loop. Wasn't sure if this was too crazy though.
