I'm guessing a lot of their content has resulted in off-topic political debates in the past That would be reason enough for a general site ban on new submissions. Most of the participants here on HN who have been here longer than I have, and especially those who have higher average comment karma than I have, are united in saying that HN is not the place for political threads. Quite a few of the experienced members of HN flag any new post that deals mostly with politics rather than with the core topics of HN, especially if the source is not a high-quality source. That gradually adds sites to the list of sites that are autokilled on submission.
