Add PubSub to the list of search builders that are getting washed and waxed by Splogs. I noted a few days ago that Feedster was getting overrun - most of the results I get from it fall into one of two buckets: ancient, or spam. Troy has had persistent, ongoing issues with Technorati, and he's not the only one.

I think it's clear that we have a major problem, and it's getting to be as bad as the email situation. Search providers are going to have to get serious about building spam filters into their engines - otherwise, we'll see all of the aggregator developers doing it themselves - which will make aggregators more expensive (in terms of system resource usage, not money). It would be simpler if the various providers did the job, because then everyone would benefit, whether they use an aggregator or a browser to view results.
