I did a test. 2 books, 2 different authors, 2 different amazon accounts (yes legit, 2 different publishers).
I had 2 different people read them, so 1 person one book, one person the other book. That was close to 4 hours ago. Zero page reads have shown up. One was a new release 9/28 the other a back catalog that has no sales or reads anymore except sporadically. So, I can be 99% sure that any page reads that show up are due to those readers. So far, I don't have to worry about it since I apparently have no reads.
