Bot Account are accounts assigned to an application that will not be limited by normal user chat restrictions. These are currently by request only. Applications should sign up for the bot accounts first and contact DLive dev afterwards.
After setting an account to bot account, previous access tokens will be invalidated. Bot accounts have following differences:
Immune to slow mode
500 characters limit (instead of 140)
Bypass Follower/Subscriber chat
Will not be Global banned (can still be banned in a channel)
