HelpGmod Cracked Server Help

So i want to make a gmod cracked server. I made a server already and my friends, that bought gmod, can join it but i cant. i didn't buy gmod i have a cracked version. I disabled VAC and in the console it says that no authentication is required to join the server. i try to join the server and it says... STEAM Validation Rejected. How Would I Make It So That I, With gmod but not bought by steam, could join my own server?

You must get a crack for serverside, or instead you could just host it inside your game
