This subreddit keeps track of submissions that moderators remove from the top 1000 in /r/all, excluding the top 100.
[position in /r/all | score | number of comments]
Think of it as an internet archive equivalent for reddit. Just because a submission wasn't appropriate for a subreddit doesn't mean it should disappear forever, along with its comments. Thanks to /r/longtail, removed submissions can still be found using reddit search.
If anything violates the rules of reddit or happens to be your own content that you want deleted from reddit, please report it and message the moderators. Make sure to include the permalink.
