I think you are misunderstanding my question

I want to do what they do in theme forest,

I could not care less about if they change the theme after they buy it, i just want to make sure they buy it, and not download it illegal
or modify it before uploading it

Try working on a theme for days on a freelance budget, I am freelance designer i need to eat so i need to sell themes,

If download a theme from wordpress and i unzipped and change for example the css, when install it, it says the header has been sent

How do i go about doing this securement, is it a theme hook, or how can put a secure pin for customers who purchased the theme

Nevermind it was theme that was adding its own search results
