I just noticed this when I saw a strange “Achievement Unlocked” notification pop up on Reddit. What do you think of this? It seems like a retention tactic to me, like what Amino had with its streak leaderboards, and GameFAQs currently has with streak achievements for logging on ten days in a row and also for all days of a month.
I’ve been very busy on Reddit lately: I actively deleted my entire posting history by hand recently - which took a long time - and I’ve taken to removing all my posts and comments the next day, or after whoever the comment was destined for most likely read it. And yet despite all my activity of late, I’ve not unlocked any achievement. How odd 🙂
