The rare occasion when one has to turn to Microsoft:
The psychology of Social Engineering - The Soft Side of Cybercrime
Reciprocity - give something to get something, give "power ranking" to get money
Scarcity - only 1000 are available, be the first to get one!
Authority - well I'm the POTUS, my patriot! you should listen to me
Consistency - you were supportive in the past you want to be consistent with your behaviour don't you?
Liking - see how kind I am, I don't forget about you I'm sending you memo, you are close to my heart, I offer you my smile, I acknowledge your support
Consensus - you are the one of many people supporting the cause and all of them want to support more
They ticked all the boxes, huh.
