There are two audios, that I think could help us regarding this part, The goal is that every person has the same intention when a video is played.
The first one is :
https://forum.enlightenedstates.com/t/justice-for-all-official-thread/24832
with each one us with the same intention, like @Forumuser said in his topic ;)
We have see with the some group that this audio playing for different as a same time it’s pretty boosted 
And the other one is “calling the alien” for help :
https://forum.enlightenedstates.com/t/alien-intercession/1582
For example, if 20,30 or more people listen to this audio. It will be like a big call for alien in the universe, and they will like “Maybe it’s time to help earth” 
(of course with the addition of powerful servitor playing this audio in different town/country).
Just some idea, but if people are interested we can make this.
