This is a big ask and maybe something bigger than just the Voyager app itself. However, I would like to see Lemmy have the same type of user level moderation tools as BlueSky. BlueSky allows users to subscribe to mute/block lists for misinformation and other types of unfavorable content that people can subscribe to. I feel that having these types of lists on Lemmy would be a great tool for preventing Lemmy from being overrun by bots and misinformation in the future. BlueSky has the misinformation blocking list enabled by default for all users as well, with the ability to adjust the settings for specific categories.
I’m sorry if this is the wrong place to request such a big feature, but I feel that such a feature would be a core part of helping to safeguard the Fediverse for the future.
Then go for the option where all the voting happens at one step based on preference. If you still want a best of two you can have the primary election earlier in the year with a score vote tally, and the two candidates that have the highest scores votes from that process then go into a head to head FPTP style for the general election.
For the record both Alaska and Maine are currently using an Alternative Voting system as well as many countries in Europe. Australia also uses an Alternative Voting system. So it can be done successfully in many countries without issue.
