So, you'll be hearing a lot from the folks at eastwikkers about frames and filters. We were reminded of this topic this week when Yahoo!'s Jeremy Zawodny began an interesting conversation about blacklisting PR spammers. Not sure this is the right way to tackle what appears to be an increasingly difficult problem for journalists and A-List bloggers, and in some cases it might even be defamatory (we'd sure hate to wind up on a list like this). But PR bloggers take note: best way to get filtered -- literally, not just figuratively -- is to annoy your peers.
