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.
This also vaguely reminds me of some advanced networking topics. In mesh networks there is the possibility of rogue nodes causing havoc and different methods exist to reduce their influence or cut them out of the process.
