the chat moderation is a "damned if you do, damned if you don't" sort of deal. if it's strictly moderated people get really bitchy when they are banned for something (especially when it's a borderline comment rather then outright "JACE CONFIRMED FURFAG XDDD"). if it isn't well moderated you get idiots spamming stupid shit over and over again in the hopes of being the one to EPIK TROLL jace. on top of that if someone is a dedicated ween it's near impossible to actually stop them from posting in chat cause youtube's moderation system is garbage.
the unfortunate truth is Jace freaking out is funny and people will use the easiest method that works to get him to do that, even if there is a huge opportunity cost. that said THE RIDE NEVER ENDS and if this stream wasn't great there will be something better in the near future
