Well if all the upvotes are coming from tiny instances, that’d be a good indicator. You can’t stop it entirely, but you can at least make it a lot harder. I do wish that instances could’ve been somewhat more “randomly” assigned to new users, as that would make any bias in voting sources a huge and obvious red flag.
Not that much harder anymore. You don’t need a good language model, just one that can spit out believable blurbs of text. Alternatively, you can do what Reddit bots do and just copy parts of other comments.
Using the comment count also promotes rage-bait, making the platform much more polarizing and toxic.
Comics are usually posted in general comic spaces. A comic that has a following is probably better than one that doesn’t, so those ones should still be bumped up in those spaces. Plus, not everyone follows individual creators even if they like and upvote all of their comics when they see them.
