I was bored and suddenly remembered that one time that Nijisanji tried to push their subreddit (before EN started) and got curious about some of the numbers.
... 2 hours of autism later, I managed to collect a bunch of data... so here you go -
Livers who still actively post on reddit(at least one post/comment within the last 3 months) -
> Asahina Akane (most active, regular posts with English translated titles)
> Onomachi Haruka (active, but just posts streams with their Japanese titles)
> Hana Macchia (caveat: she hadn't posted for 7 months before her b'day post. Total 8 posts and 1 comment)

Nijisanji made a company wide push for reddit back in December 2020 (even Riku posted), but it was in the form of literally EVERYONE spamming "hello! I'm so-and-so" posts.
There were 1hr difference in posting "slots" which can be observed based on the time of the posts.
It may have been management mandated, because despite about 30 different accounts spamming the entire subreddit during that time, only 2 of them remained regular posters.
