Probably better to post in the github issue rather than replying here.
seems trivial to check for a login/subscribed etc. then increment up//down votes. why link each vote to an account in public? maybe for mods an account(s) to be banned for botting votes?
Because then people can vote an unlimited number of times.
There needs to be some sort of identifier
array votes[post_id, vote]; // for storing in user profile not public but can be hashed if you don’t trust your dba
Enumerating every user to get the vote count on every single post/comment seems too computationally expensive.
