Do an mctop and /jobs stats duppreh. Ask Duppreh why he gave himself $1 per cobble and 1 exp per cobble while he leveled to level 50 miner then reduced it to .10 per cobble. Ask why the end is only for the owner and his friends.
Any server where the owner uses a efficiency 9 unbreaking 9 fortune 9 diamond pick to mine then prevents anyone from doing as good as him is not a good place to play, if you want to be treated fairly. Sure mobs drop wooden and maybe even occasionally iron picks with high values of respiration or depth strider, but not diamond picks tailored to mining.
Any if you play legit, in any way that is successful and does not involve giving yourself an OP pick, you will be falsely accused of hacking and banned. Anything you get from the "Christmas event" will just be bought with the infinite hacked money of the owner and his friends, while being careful to not inflate their baltop.
Your choice. I am just sick of servers like this.
