I re watched the video real quick Labeled you are correct that it is a true reaction and not spliced I was a touch trigger happy because of a similar instance that happened with Lasarbeam. although you can clearly its not Shrouds youtube and how does the fair use work out for instance if you record someone recording someone else like shrouds twitch reaction is transformative hence legal in the US but the recording of the stream by someone else isnt?
mostly I posted in here if LTT didnt know about and saw this and wanted to anything about it its their prerogative to do so
