huh I suspected about 200 too, and it was 320....despite me clicking unsubscribe constantly over the past few years. I must have been about the same as you at the peak.

But really, I feel like reddit's algorithm is really shit & doesn't show you any content from some of them for ages at a time. For example, I was in /r/DotA2 still despite not paying much attention to that scene/game since like TI6 or so. I doubt I'd've stayed in it if they ever showed me posts from there. On the flip side, I feel like I rarely got comment from /r/lifeofnorman (like couple times a year) even though it's always been on-and-off active, and I adore that subreddit.
