I voted for "more than 2", because this is my answer to the question as it is posed. But since I was arguing for a possibility of one person solutions, I'll elaborate.

I can't exclude any number in particular. This could be a single person who had too much time on their hands. But I also have a pet hypothesis that the center of You are not allowed to view links.

Maybe even including the alphabet as written by each of the authors, hence 4x17 feature. Two of the authors hid their faces, and two are shown openly, maybe because they are not afraid of prosecution for some reason. Or maybe these two shown persons are dead, and the authors are two persons whose faces are not shown.

So, I'd say my probabilities are 20% for a single author and 80% for more than 1 author with the peak probability at 4 authors.
