As other users have pointed out, it's not particularly rare, because they produce good articles semi-regularly. We were discussing this the other day: https://news.ycombinator.com/item?id=10405992.

Sites that are mostly junk but also put out the occasional good story are a significant problem for HN. We can't ban them, because losing good stories is worse than tolerating bad ones (the latter are annoying, but get flagged). Our solution is to penalize them, review the stories, and take the penalty off the good ones. The next step will hopefully be to distribute the review process to the community.
