Amanda, Frank, and Michael are 3 users on Stack Exchange. One of them was serial down-voting. Can you figure out who the culprit is?
Amanda has been suspended for sock-puppetry numerous times. She has over 35 different accounts, but the exact ones are unknown.
Frank’s posts are often flagged for spam.
Michael is an old user. He’s been on Stack Overflow for over 8 years, but recently his account has seen an increase of down-voting for no apparent reason.
Given the evidence, who do you think is the most likely person to be the serial down-voter?
EDIT #1: We seem to have lost some of the original evidence. Good thing it was logged here: https://puzzling.stackexchange.com/revisions/-----/2! Some user, who may or may not be responsible for the serial down-voting, physically damaged the webpage. The only evidence remaining on that page is a pair of scissors.
EDIT #2: The question ID (in the evidence link) is missing and cannot be recovered. Can you figure it out?
