I NEED YOUR HELP!!!

I just ran into a copyright problem. Long story short, there a guy posted my mod without permission and i already told him to take it down and gladly he did remove it. But this problems might happen again anytime anywhere.

So I NEED YOUR HELP on 2 topic:

1) Is there any ways to prevent this problem or at least minimize it, I will add watermark to the mod code.

2) Should i post the released mod to gamebanana?

Thanks for your time and any idea counted

Love

Ark
