The hacks can be so easily patched (once and for all, not just a simple "update" through changing the addy or w/e), but Z8 has no developers, and X-Trap/HGWC is a side game security program, so they have no interest in patching many game-specific hacks.
I one time offered to help, but they said to go to the developers, SmileGate, which is a Korean company.
