This will probably break or get patched extremely quickly but I don't really care.

This is a Tampermonkey script which enables viewing of censored ("blacklisted by default") posts for users who aren't logged in. Tampermonkey is an add-on available for Chrome and Firefox which allows convenient injection of third-party scripts in to websites to modify their behaviour and functionality.
The script only functions on the post search pages, and image viewing pages. Pools remain censored.
Due to a lack of efficient way being too lazy to use the right API to get all information about a post on the search pages, the post status (including border colour), score, comment count, and favourite count, are all missing on the posts inserted by the script. Censored video posts aren't directly supported, you have to use the "Download" link.
For both logged-out and logged-in users this also re-adds the "Uploader" field to the sidebar. The script shouldn't have any impact on logged-in users otherwise.
