The votes in all these posts look like this. In this example, only two of the downvotes look legitimate. The rest are coming from three instances that don’t appear to be real Lemmy sites. One of them doesn’t even resolve.
This is correct, with the caveat that the votes must have federated with the admin’s instance (so other instances need a user to be subscribed to the community in question, and votes can take time to flow through).
