Allows commenter filtering on The Stranger's online articles and blog posts
This userscript improves the user experience of reading comments on The Stranger's online articles and on Slog and Line Out blog posts.
Through DOM injection, this userscript provides "hide" links next to each commenter. After hiding a commenter, their comments are seamlessly collapsed on each page load. A list of hidden commenters is also injected into the right sidebar.
This userscript converts the flat, numbered comments into manageable threads with nested replies, using cues like "@4" or "#7" in the comment text.
