Alright, there are differences in getting strikes, claims or revenue taken away.
I think as long as you comment another video you won't get striked or claimed, is this true? I just saw someone do a reaction video to some cartoon, and they said "As long as we comment it means we can show wtf we want..." However.... question would be, can they still earn money from this 'reaction video'?
I have got some videos that have got a large amount of views but they have taken the ability of earning money from them away, but they haven't deleted the content from my channel.
To be on topic, if I would now 'react' to let's say "Terminator 6 trailer", by showing the whole trailer while having my facecam attached to the video, I can still show this on my channel, but I can't make money out of it? Or will it also be copyright striked maybe?
