Yeah, that's not LJ, it's the source of the feed. That happens to me here, and I've had to dump several feeds because of it. Raw Story, for example, has a habit of not bothering to proofread anything, and then when they do corrections, it's like one typo at a time. Trouble is, they insist on re-bumping the story on their feed every single time, whether it's a significant update, or a trivial edit. The result: a dozen entries for the same damn story jamming up my friends page. Mac OSX Tips does something similarly annoying. Every so often, they'll re-bump several months worth of entries all at once. Page after page of old news. Infuriating.
I've occasionally had large clusters of feeds re-appear on my f'list. It's a recurring bug that I believe is fairly low priority. (Because unlike comment rot, it doesn't keep people from wanting to be here, and it doesn't happen often.)

But this time I think it is LJ's fault.
