I spent ten years on Reddit. I can use that to compare for myself the amount of engagement then and now.
If most of the users are not bots I would be so surprised. I think they lost a huge percentage of traffic and are now knowingly faking live user counts
Reddit also grew to 97.2 million daily users over the past few months, marking a 47 percent increase from the same time last year.
This is for the quarter that covers July, August and September. Last year, the API fee kicked in on July 1, killing most third-party apps, and the quarter would have also included any lingering drop in users from June's protests. So, it's a big year-over-year increase in daily users but that's compared to what might not have been a very good quarter last year.
