If You put a topic, for example during End Game, about Goods to haul Online and Offline... any troll can come and spam the topic.
Simple solution would be to enable city council to make topic, where only city council can post things. So they they can post info there, without other trolls to spam there and discuss off-topic stuff.
Same for in-game association's forum, topics where just deputies can post things.
Same for regions, topics where just cabinet members can post things.
Simple. Easy to work. Make in-game communication better.
