The best part of the fediverse is that anyone can run their own server. The downside of this is that anyone can easily create hordes of fake accounts, as I will now demonstrate.
Fighting fake accounts is hard and most implementations do not currently have an effective way of filtering out fake accounts. I’m sure that the developers will step in if this becomes a bigger problem. Until then, remember that votes are just a number.
The lack of karma also makes it worse. Usually if I saw a discussion that felt kinda off I’d check the accounts age and karma. Made it easier to sniff out bots.
