Minecraft 1.4.7 HELP

I need a hack to hack into the console of this server: 198.24.163.22 It is a pixelmon server. And basically what they did was. I build there,did allot of stuff for the server. And once i was done with everything they threw me out. Got rid of my stuff. Reset my entire pokemon and inventory and enderchest, and that was over 2 months of work. So i want a payback... I need help from anyone who can do this or has a hack to this...

To get my stuff back and also to let them know. Not to fuck with me....
