the video doesn't really say anything about the two people, they happen to move the same pattern, that's all. If anything, that Rhisan guy on the left side of the video would be more suspicious, because I can't imagine people spam w and s in a rate like that for a long period of time. If that guys been hunting like that for hours, he's a bot, because to move like that you would actually have to spam w and s very quickly for a very long time. When I hunt, I just find a piece of grass so I can go all the way to left and all the way to right to minimize the amount of key spamming, instead of moving in the same two-three cells back and forth(it's really hard and tired to do that).
