You can’t fight against it. That’s the point. The only tactic is to stay stealth as long as possible.
You won’t win with barrage of AI generated content and massive corporate machine of marketing. No filters or countermeasures are enough against the brute force of money. Not to mention Lemmy is relatively easy to spam and troll compared to Reddit if someone wants to do it.
It’s vulnerable by design because the same vulnerability is a feature of freedom of speech and openness when there are no bad actors.
It’s kind of like anarchism if you think about it. Great concept but collapses from miserable human condition.
I predict we will all(technical hyperliterates) be on some form of TOR sooner or later because that’s the only place where advertisers and ai won’t dare to go.
