I don't know which would work for you. But here https://servers-minecraft.net/minecraft-smp-servers I saw a great bot for chatting and voting. I advise you to contact them about this problem. They have a very responsive administration there. They will be glad to listen to you and help you. I play there for a long time and everything suits me. First and foremost the administration, as I said, and secondly the very players that play on their servers, there are almost no toxic players because of which you do not want to go more of the server. The administration takes care of that. Third, the servers themselves are made at a high level.
