Evenbalance rarely divulge what their codes actually relate too so we're in the dark as much as you are.
Any 3rd-party ban site, such as PBBans (this one) , GGC or AC I has to take the violations that PB comes up with at face value and even though they aren't privy to the reason behind the ban, they just enforce it and add it to the Master Ban Index (MBi) which streams to all streaming servers.
I feel for you, especially if there's a wrong doing as there can be nothing worse than being accused when innocent, but we're just protecting our servers by going by what the employed anti-cheat (PB) says.
