It’s home to a very strange community that was unaware that their “platform” was just an image host for users of an actual social media platform. Well, at least it was before imgur recently started adding social media features and purged nsfw content.

Popular image posts from reddit would routinely get boosted (sans context) to the top of imgur’s homepage, attracting confused, angry, and often unintentionally hilarious comments from imgur users. Iirc there was a subreddit dedicated to this phenomenon.
