My ign is JhowTheWaffle and there was a hacker (SamLourson) and he was in a impossible place to be as there are barriers blocking the way up there.

 

This evidence of not sufficient. There is sometimes lag that makes it look like flying. I can't really tell considering how close to a block he is. It may just be a glitch that gives the allusion he is hovering on the log. PM me if you have concerns.
