Keeping things simple.
Reddit had ways to automatically catch people trying to manipulate votes though, at least the obvious ones. A friend of mine posted a reddit link for everyone to upvote on our group and got temporarily suspended for vote manipulation like an hour later. I don’t know if something like that can be implemented in the Fediverse but some people on github suggested a way for instances to share to other instances how trusted/distrusted a user or instance is.
Not to mention Lipton Ice Tea is rubbish. You can make your own for 1/10th of the price, and it’ll taste 10x better.
