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.
And it’s only a matter of time until that detection can be evaded. The knife cuts both ways. Automation and the availability of internet resources makes this back and forth inevitable and unending. The devs, instance admins and users that coalesce to make the “Lemmy” have to be dedicated to that. Everyone else will just kind of fade away as edge cases or slow death.
