The joke comes from an increase in bot use on Reddit, and the subsequent false positive / false negatives in trying to figure out which ones are bots
Lemmy has that problem too, but it's much smaller in scope. Mostly because there's less of a reason to try and control the narrative on this smaller platform, but also because the goals are different. Lemmy instances get no benefit from a bunch of fake engagement, and public upvotes makes it easier to catch manipulation
Most users on Lemmy are Delusional. especially here in /c/Technology -- turns out, this community isn't for technology at all, but rather for bitching about silicon valley companies.
