Some streams require Facebook Connect in order to use their chat channel. Is there a way to detect this via the API or some information on their twitch page?
For example: http://www.twitch.tv/esltv_lol requires facebook login and http://www.twitch.tv/esltv_sc2 does not.
The message when you try to type in chat is:
You must Facebook Connect to send messages to this channel. You can Facebook Connect in your twitch settings under the connections tab.
