Did you know you can run the chain in-reverse and turn it into a filter? Finding a good threshold one-sided can be hard, but this is basically how a lot of spam-detectors work: They record the chains seen in /g/ and the chains on /pol/ and now you can make statements about which board the comment probably belongs on with, simply by doing some analysis on the frequency of chains seen in one corpus versus another.
