I'm a data hoarder. I like to go through the Popular posts for every day, pick out the ones I like best, favorite them, upvote them, and save them locally in case of deletion. I keep an account of which day's popular posts I viewed last, which for me was July 30th. I logged in today to do my hoarding routine, and noticed I had favorited a post that I don't even remember seeing. The post in question is https://e621.net/posts/3487027.
Information says it was posted less than 24 hours ago. I have not been on e6 in the last 24 hours, or at all since August 1st. How could I have possibly liked this post? I assume if my account had been hacked I would've seen some other fishy activity on my account, but nothing seems out of place.
Is this a bug? Is it because the post is a replacement for a previous post? I'm so confused on how this happened.
