didn't try to use it but i think you can eliminate d.buzz from your peakd feed.
d.buzz is a community hive-193084 so if you go to settings/content you have an option to "Hide posts with a specific tag or category from your following feed"
i did not use it, and i don't see a lot of d.buzz on my feed, maybe i will test it out, but in theory if you put "hive-193084" you should not see d.buzz on your peakd feed.
