You're not going to be able to post your hack client on Newgrounds.
The Newgrounds rules state the following;

Rights and Ownership

You must be the creator and owner of the game you are submitting.

You must have rights to the music in your game, or be using music that grants rights freely. Your favorite song from the radio can't be played here.

Your game must not be a modified version of someone else's work, including tutorial files.

Your game must not use Angry Birds or Super Mario Bros. characters/sprites. In general you shouldn't be using any sprites you don't have full rights to.

Do not include copyrighted video clips or photographs that you did not create.

Basically, if you even dare to post the hack client on Newgrounds, it's going down.
And if you wanna know where this information is coming from,

There you go. Also, notice the part 'Your game must not be a modified version of someone else's work'? Yeah, that includes your hack client.
