Yeah, but I don't think they're trying. This is a tactic frequently used on forums like 4chan where they just flood you with copy pasted nonsense to waste your time and discourage discussion. They know what they're doing and are acting like that intentionally, which is why I'm worried about this becoming normalized on lemmy.ml. Hopefully it dies out just like the Ukrainian counteroffensive.
They'll probably filter away away to other instances that block lemmygrad I imagine. Or more likely, go back to their reddit echo chambers where they can feel smart.
