First post/new account so bear with me.
My IGN: JustNoOne
So, just a few hours ago witnessed a player named "parx_boiz" complete /checkpoint2 in parkour by spamming cobblestone below him to get up the last jump.
I don't have a screen recorder and I only took 1 screenshot cause Admins Zarosi And Brenda were online so i /msg them.. unfortunately Brenda was in Mob arena and by the time Zarosi replied parx had already passed it, took the rewards (probably) and logged off.

I bought it to both their attention and am positive it will be handled but I just thought of posting it here so there is a permanent post to look at the screenshot n stuff. So yeah Thank you.

P.S. - I realize I should have taken more screenshots but like I said I thought since admins are on they can just tp and catch him in the act. It was a mistake on my part. Apologies for any inconvenience.
