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.

I see your point... votes from a compromised instance (or instances) and such. How is this more or less vulnerable to a centralized model?

I'm not a security expert by any means, though I would imagine this type of attack can more be more easily made harder to execute if all accounts have to go through one server first. Lemmy seems to be as strong as the weakest link in this regard, but a centralized model is just a single link. I imagine that any effective strategy that works for Lemmy is much easier on a centralized platforms, even though the reverse statement isn't true.

That said, I'm optimistic that this gets figured out. Centralized platforms have had decades to solve this problem and we're just getting started.
