I want to draw attention to the elephant in the room.
Leading up to the election, and perhaps even more prominently now, we've been seeing droves of people on the internet displaying a series of traits in common.
- Claiming to be leftists
- Dedicating most of their posting to dismantling any power possessed by the left
- Encouraging leftists not to vote or to vote for third party candidates
- Highlighting issues with the Democratic party as being disqualifying while ignoring the objectively worse positions held by the Republican party
- Attacking anyone who promotes defending leftist political power by claiming they are centrists and that the attacker is "to the left of them"
- Using US foreign policy as a moral cudgel to disempower any attempt at legitimate engagement with the US political system
- Seemingly doing nothing to actually mount resistance against authoritarianism
When you look at an aerial view of these behaviors in conjunction with one another, what they're accomplishing is pretty plain to see, in my opinion. It's a way of utilizing the moral scrupulousness of the left to cut our teeth out politically. We get so caught up in giving these arguments the benefit of the doubt and of making sure people who claim to be leftists have a platform that we're missing ideological parasites in our midst.
This is not a good-faith discourse. This is not friendly disagreement. This is, largely, not even internal disagreement. It is infiltration, and it's extremely effective.
Before attacking this argument as lacking proof, just do a little thought experiment with me. If there is a vector that allows authoritarians to dismantle all progress made by the left, to demotivate us and to detract from our ability to form coalitions and build solidarity, do you really think they wouldn't take advantage of it?
By refusing to ever question those who do nothing with their time in our spaces but try to drive a wedge between us, to take away our power and make us feel helpless and hopeless, we're giving them exactly that vector. I am telling you, they are using it.
We need to stop letting them. We need to see it for what it is, get the word out, and remember, as the political left, how to use the tools that we have to change society. It starts with us between one another. It starts with what we do in the spaces that we inhabit. They know this, and it's why they're targeting us here.
Stop being an easy target. Stop feeding the cuckoo.

Yep. It's a damn mess.
I don't claim to know how to make them be honest about their motivations or, in the case of those few who are genuinely being taken in by this garbage, wake the hell up and realize what they're throwing away. But I know that having the idea out there in the open in a digestible way can at least help some people get a better view of what's going on. Maybe they'll follow suit and block some of the worst ones. Maybe they'll rely less on social media for their perspectives on the world and realize that Lemmy isn't the exception to its toxicity just because it's open source.
We need to be more aware of them than we have been, though, because it's getting worse.
I just don't know a good way to deal with that, TBH. I wish I did.
It's tough. If I get a funny feeling about an account and think they might be a concern troll (I think that's the term that applies here; if not, someone please correct me. I think "false ally" is a sub-class of that, but I'm shooting from the hip here),
I'll typically look back through their history, try to put things in context, and get a feel from there. The ones I blocked were pretty much all one-trick ponies, so that was easy (though tedious as it took a while "vetting" each one).
The problem there is, yes, you've identified that person. But everyone else needs to do the same legwork and come to the same conclusion. You can't just put up a sign that says "Troll" lol. Depending on the community/instance, you could report them, but that often puts mods in a sticky situation because they usually don't want to suppress anyone's viewpoint as long as it's not violating any rules.
That's even tougher. First, you have to figure out if they're the troll or the one who was trolled (troll-ee lol?) . And one, very rightfully, can't /shouldn't just start calling people trolls or shills. For one, they might be the troll-ee; going out of the gate with name-calling and accusations is definitely not the way to convince them to re-evaluate their views. For another, it just sets a bad tone and gives the impression that "everyone who disagrees with me is a troll".
But sometimes they are. What do you do then?
Wish I had an answer that didn't involve writing multiple theses on a number of topics as they try to sealion me into submission lol.
So, everyone actually doesn't have to do the same legwork. If most of the posters in a community block someone, that person won't be able to post in most of the threads in that community and won't get the engagement they're looking for.
Whether they're trolls or whether they're useful idiots, I say block them. Not only that, actively encourage others to do the same. If we take to blocking these people on sight the moment they start spouting this bullshit, they very quickly will see threads full of "# additional responses" that they can't actually see or respond to.
In some cases it might actually be worth reporting them, too. A lot of them go well beyond the rules of the communities they're engaging with, but I've also seen at least one instance where a very prominent cuckoo-poster got chased off the instance by the staff. He was basically told to knock it off or leave and he chose the latter. Good riddance.
Don't the people you block still see your posts?
I'm under the impression that they can't reply to them directly.
