I like and boost my posts for visibility but my comments I don't. PSA: you can see who upvotes and downvotes any post or comment by selecting "more" and then "activity". I can see you upvoted your post, for example. As far as I am aware, this is a kbin thing-- lemmy does not make this visible to the user.
And I think it might as well implement an automatic upvote for everything, like reddit and lemmy (or lemmy.world, anyway).
Maybe I'm overlooking something, but isn't the actual change that doing these things will no longer be a viable way to earn a living?
