If I read what you are saying right, you have an account, may I call it “MyBotAccount” for the purpose of this reply? Now, you want, say, 5 other people to also use “MyBotAccount” for their chat? While I won’t comment on the ToS, do keep in mind that there are global chat limits and if the bot responds at an expedient rate that I believe it could be possible that it could get a short term ban (30 minutes if I remember right but, perhaps someone else can chime in that knows this better than I do).
