Can auto responses be limited to some members?

Yes. Each auto response is gated by a role, so only members with that role trigger it.

Can I change how the bot looks in my server?

Yes. A per-server message profile sets the display name and avatar the bot uses.

Let the bot handle routine messages and reactions. Set the rules once and Dungeon Keeper answers, reacts and announces on schedule.
