This is about all the trouble you have because of the spam on the Twitch chat, I just wanted to suggest that you guys get an IRC server chat room setup. The Twitch.TV chat is horrible, there's no true way to control it, however, an IRC chat allows for all kinds of things, from plug-ins to programmable crowd-control bots. I just wanted to suggest this to make the give aways easier on everyone, as getting rid of spammers would be a ton easier (heck, you can even ban singular words from being spoken on the chat, preventing people from posting the keyword 200 times before it's the correct time to do so). Thank you for your time, and I hope you all have great TF2'ing days.
