Because you pretty much need a seperate Lemmy, Kbin and Mastodon account. I’ve heard that it’s somehow possible to see Lemmy posts from Mastodon, but I haven’t really been able to understand it. Apparently, it’s janky as hell, but I wouldn’t know, as I just have 3 accounts I use, one for each ‘service’.
Since I moved during the Reddit fiasco when servers were overloaded and didn’t know what I was doing I just hopped from instance to instance. So now I have at least 7 dead accounts that are still probably counted in the ‘users’ statistic.
I’d say one person counting for ~10 is significant, and I doubt I’m alone, even if I am an outlier with my instance-hopping
