I've noticed a ton of these too: it seemed to have started right around New Year's.
As someone who typically scrolls All, I'm not even sure if it's specific to this community. There are a lot of Comic and Meme communities where these things are getting posted across various instances. I'm still not sure whether this is nefarious or someone trying to grow Lemmy. Could just be some college student trying to test out making bots, posting things they genuinely like. Though I have noticed most of the comics tend to em have divisive elements or say things that are obviously wrong. It seems like their goal might be to drive comment engagement.
So I've been marking them with UserNotes as "Comic Bot" and usually just do voting and moving on. Occasionally commenting to draw attention to the user history for others.
I mostly agree with you, but I don't think this is just a distraction story. The more interesting thing is the rift forming between MAGA influencers. Candace Owens clearly has beef with Erika Kirk.
