I’d avoid hot. Unlike Reddit’s sort of the same name, Lemmy’s hot gives a lot of weight to brand new posts. I regularly saw lots of posts with no votes when I used it. Active or top is probably safer. Though admittedly, if someone is using bots to post content, they could use bots to upvote, too. Lemmy has pretty much nothing to prevent even basic botting. The way federation works is actually way worse for the ability to prevent bots, because bots just need any insecure instance and can spin up their own instance in minutes if they can’t find an existing insecure one (at the cost of burning a domain).
