Show HN: A script to move links on HN to undesirable sites to the bottom (github.com)

I would retitle this to "A script to move links on HN to paywalled sites to the bottom"

I would also suggest maybe just highlighting them in some way, because while for you the paywall might be undesirable, to paying subscribers, or even curious readers who just want to peruse the comments, it would be nice to know the site is paywalled first, but still that it is a high ranking item.
