A question, per your final comment on being available to answer questions:

What do you feel is the benefit to the community for this that isn't offered by native blocking/existing extensions?

I ask not out of malice, I ask because 2 reasons: 1. I imagine spending time on this/it's working well required you to see the value/benefit to it. 2. We must assume all hacker news commenting follows the rules, IE; good faith comment with relevant experience when required. This seems like a way to promote getting around that.

> that isn't offered by native blocking/existing extensions

There is no “native blocking” on HN. You cannot block a user or hide their comments and submissions in perpetuity. You can only hide on a per-story basis.
