Looks like @zakir43part2's comment is made with the esteem-app. Using the app you get random upvotes from these accounts, so nothing to do with Zakir. :)
Anyway, upvotes don't count it this contest. A "Vote" is a comment from another user with the word "vote or voted". And also, this comment wasn't an entry in the challenge. There is another comment below from Zakir.
Hope that clarifies.
