It actually irritated the folks who joined the preliminary race but couldn't land the top 5 spots, as well as those who did win, and the JA staff who were watching it happen in general. But that's all in the past now, and like vexon said, there was no damage on the stream and it still ran smoothly, which was the objective of ToTH. Remember, it was for the kids. Anything else is secondary.
We'll have a fool-proof solution with the whitelist plugin for future events, so no more fuss is needed.

Another issue I noticed is the loss of time keeping may be improved by not actually have the coordinator for the segment be in-game on the stream. Vexon had his hands full talking on the stream to notice the time that has passed, and couldn't respond of any concerns I made in chat without interrupting the flow of the stream.
