First of all, thanks @cityhelper for giving your statement on the situation. Yes, I know your merits in the dCity community. Yes, I'm also a daily user of your Discord bot.
In my opinion, it is wrong to request mandatory donations (I even doubt that building the @homeless-city can be considered charity). Your two options looks more like extorsion (donate, or I will destroy the game for the rest of my days as president). Yes, @homeless-city was built from donations, and it is itself an interesting experiment. But building it does not deserve the agony of all the small and medium players.
You were elected president by following all the rules. Also it is totally in the rules that the President can change the taxes to 100%. I don't accuse you of disobeying the rules. I'm only interested in the philosophical debate, very actual also in many real life situations: how to make elected officers accountable for the promises they do?
