The very very short TLDR is that anonymization is very hard, but there’s auditable cryptographic voting schemes which preserves anonymity by using anonymous cryptographic commitments and one of a bunch of different techniques to count encrypted votes (homomorphic encryption, threshold encryption, etc).
You could set it up so you know which server each set of votes comes from but not which users on the server. You could also make it prove each vote comes from one real account and that no account voted twice. You could even make use of commitments plus ZKP to prove banned accounts can’t vote!
It sounds complicated because it is complicated. And somewhat inefficient. But it’s possible. And it would be fully encrypted and anonymous voting.

How would it prove that the account is real? I suspect that the meaning of “real account” is not the opposite of bot or sockpuppet.
