Fair enough, you might not have specifically said “bot” or “Russian”, but this idea that there are pervasive influence campaigns everywhere and that people who comment against you aren’t being honest is the core of the problem. Unless you’re really pulling in some nonstandard tooling and doing some additional analysis on posting times and finding template wording (not just people using things epithets like “Blue MAGA”), you really don’t have any ability to sniff out fake posting from just people you really disagree with.
Someone coming on Lemmy day after day to diss the Democratic party may very well just not like the Democratic party. I have some people I follow on Mastodon that have radicalized over time. They were real and slightly cynical posters who just got more and more angry at the way everything’s turned out. And on the other hand, I also have people I follow who spend half their time just repeating Democratic party influencers. That’s not fake, that’s just a particularly clunky form of memeing. And still others who very deliberately want to spread their political view by whatever means are optimal. That’s maybe manipulative, but that’s also just another method for political persuasion.
This whole core of this post reads like “I like this, BUT there are totally fake posters and we need to call them out”. This strain of dialogue isn’t unique to Lemmy, it’s basically everywhere in public discourse and as I said elsewhere, poison to it. Because you’re not going to prove it. In all likelihood you’re probably wrong, as most influence operations were simply enhancing existing positions and thus largely indistinguishable from them. You’re just going to get people who also dislike the target saying “hur hur, they sure are fake” and the other side saying the accusations are insane, and then devolve into increasingly acrimonious back and forth taking up half the comments on a post.
