There is a certain guideline for wc3 maps. If warcraft 3 can open it, so can a user.
Best chance to hide an activator in my opinion is to use encryptors.
I recommend you take a look at power towers to learn about that.

Is there a different way to learn about encryptors? I'm not really that ''good'' at analyzing other maps, like Power Towers. :/

JASS is coding, just like any other coding language (sort to speak)
If you know other languages like Visual Basic it will be understood (for the most part)
Making an encryptor \ decryptor using jass is just like any other.

If you don't want to learn jass, I am sure there are many other guides for how to make an encrypted key (like a key-gen...)
I don't have resources to give you tough, google is your best option there.

Thanks for your information! I will do my best.
