This. We as a community can do our part to downvote bad info (at least on kbin, idk if Lemmy has downvoting or not) and commenting to let people know what's up--but that will only go so far and we're not gonna catch everything. We can also report harmful misinformation that we see, but all the same, plenty of users will still receive and buy into it before it's dealt with. We need well-moderated communities for a reasonable level of peace of mind.
