MyChat Rights group: "Moderators", "Right to kick users from the text conferences (kick)"
If a conference moderator has this right, then he can kick any user from a text conference (except for himself and built-in bot Elisa (UIN 0).
A kicked user can enter a conference again. If you do not want this happen, then you need to ban him from entering a conference.
