Blockr

A simple, lightweight post blocking solution for Tumblr

Blockr is a post blocker for the popular blogging site Tumblr. This extension adds a small button to each post which blocks the post from your dashboard. Posts are blocked based on their root post ID so the post will be hidden no matter who reblogs it. The block button is located at the top right of each post so users can block offensive or unwanted content without having to scroll through the entirety of a post.
