I have looked in to the code and although that could possibly be a reason why people leave without their own accord, AgentGod's hack disables the "leave game" button through .dll files I think, however unless you are really skilled then that is kind of a longshot from scratch coding, due to the fact that VAC will automatically ban you if any .dll files are different from what they have allowed. Now that i think about it you can use your own tool to bypass the VAC ban, regardless of whether it is detectable or not
