Additional info:
I'm Psycho_Pyro, I just joined the server today and spend almost 4/5 hours building a house in the PvP area...
I made some friends, met some people and my house was starting to shape up real nice...

Ari came by, flew around a bit and placed some torches to keep the zombies away, I kept building and helping another dude teleport to me once and a while... Ari came back and placed a few heads down on some fences for me while I was finishing up some details of my house...
I asked Ari to remove the heads again (Because I wanted to expand the deck a bit) and all of a sudden I got the following message;

Banned:
Admittng to using hacks; Screenshot proof provided.

Now I have no clue why I got this message ? I have never used hacks in my life and no one talked to me about me hacking or whatever... also I have no idea what screenshot... I would like to see it so I know why I was banned... like I said I really have no clue what happened here...   I'm using a pirated minecraftlauncher and launch minecraft via forge.

I feel really sad because I was so pleased with my build and was actually having fun with some people... and all of a sudden just poof I got banned

Anyway I hope you understand my sadness and confusion and also understand I would like to know more about this matter...

Kind Regards,
Psycho_Pyro
