Those 11,727 people watching are surely confused about what they are watching, I mean who could have tell them if those offers are true or false? if they don't know what's really going on, they might fall to the trap of the scammers.
Most likely, the fact that they watched the live streaming, that means they are interested with it and you are right, they might fall for the scam.
Since this guys are confused, is there any way to tell them that those giveaway is not true?
I expect that there are people in the chat that works for the scammer will try to convince people to invest or give some testimony that they receive the money. They have already planned all these things, and if someone watching is telling it's a scam, it will not win against the scammers as they have people and since they own the channel, they can kick anyone in the chat room I guess.
