Hide annoying posters on BigBlueInteractive.com.
Pretty much the most valuable browser extension ever.
version 0.0.3 supports storing a list of users to hide (separated by commas – spelling and case matters).
Just click on button in the extension while on the front page and the posts of those on the list will be hidden.
While reading a post, click on the hide button to hide comments from posters on the list.
Now supports auto hiding. Click on the icon to have the option to toggle the hide/show preference.
