Reddit Restore Blocked Comments от Stouty

When a Reddit user blocks you, their comments are hidden and replaced with "[unavailable]" on old.reddit.com. This extension automatically restores those hidden comments and usernames using the Arctic Shift archive, a public database of Reddit content.

What it does:

Detects comments marked as [unavailable] due to block relationships
Fetches the original comment text and author from the Arctic Shift archive (arctic-shift.photon-reddit.com)
Restores the comment inline, with a subtle orange border to indicate it was retrieved from the archive
Works on page load and when loading additional comments dynamically

What it doesn't do:

Collect any user data
Restore comments that were deleted by the user or removed by moderators
Work on new Reddit (only works for old.reddit)
