I'm guessing it's the dude that used his GF's photo to get likes?
In all honestly they shouldn't allow for photos like that. 1. because, like you said, there's no work out buddy. 2. People are liking it for another reason besides the purpose of the contest.
There's also others who are just posting themselves and others who are posting unidentifiable photos.
@AnkerOfficial Please consider the actual winners instead of going by "The entrants of the top 10 photos will win." There's like 5 people out of the top 10 who aren't even trying to follow the rules.
