i’d wager that one or both of your topics read and posts read counts are too low for the past 100 days. remember, it’s 50% of posts/topics in the past 100 days read, and (from my observations) you have to hover over a post for around 3-5 seconds to have it count as read, so scrolling through a bunch of posts without actually reading them doesn’t work.
i think there may be a posts created requirement but i’m not too sure on that. the likes requirement is fulfilled for now, but you should get to liking some posts since the last post(s) you liked was(ere) on the third of june.
