[COMBAT SURF] I am confused on why I got banned

[JabbaK]

I am confused for the reason I got banned. It says 'Steam Community Group Ban (atorcommunity)' 

I do not know what this means or why I got banned but on the fourms it says that one can get an appeal so yeah.

And If I do get unbanned may you explain why I got banned in the first place so I don't come across this mistake again.

And even If you do choose to not unban me I will make a vow never to touch matrix serf
