Ever since Reddit's inception you used to be able to search Google with a query like the following:

"site:reddit.com/u/SuperConductiveRabbi" (or with /user/ instead of /u/)

This would return a majority of a user's posts and comments, as seen on their profile page. It was extremely handy for finding a comments you remember seeing a user write (including your own comments, and Google's search was vastly superior to Reddit's shitty and broken one).

Today Reddit's admins have disabled this functionality, and Google's cache of all user profiles now seems to be purged. You can't search for your own posts or that of any other...and, notably, you can't use Google to see user content that Reddit admins decided to delete.

This change is already having a negative effect on finding information about why users have been banned, as within the last 24 hours the Reddit admins banned an /r/undelete user who criticized /r/politics for censoring anti-Clinton material (discussion on /r/undelete). His user page on Reddit is now invisible to Google.

I also posted this to /r/undelete
