I saw Reddit's anti-spam internals.
Getting these notifications wasn't unusual in and of itself - I was a moderator of a few fairly small subreddits that'd from time to time get posts automatically removed for spam.
However, when I went to actually look at the removed spam, I saw something I was never meant to see.
