Kicking in chat is pretty useless and/or pointless. Everything that happens when you are kicked is, you are sent to the room list. There's no kick message, no "kicked by" message, no kick reason, nothing. For all a user knows, it's either a transient bug or a network hiccup. How is that useful?
The user can also immediately rejoin the chat. There's no repercussions for the user being kicked, it's just annoying. Even as a mod-only tool it's basically useless and annoying/confusing rather than a helpful moderation tool.
You may want to consider either removing it, or turning it into something more effective -- maybe user-specific room-specific 30 seconds long silencing.
