Arma 2 Server Hack

If i installed the Server Hack to my Server can i go spawn anything with my not gb Key or can i get banned?

If battleeye is on, then you'll get your ban. Haven't tried server hack, so I don't know what could happend really.

Once you have whitelisted your name and GUID with the Arma 2 Server Hack then you are free to spawn anything and everything. The entire point of the Server Hack is to hide your name/GUID from Battleye so you don't have to worry about detection.
