I believe that "hidden contact form" may have a use if build intentionally.

I had a similar (but intentional) idea with "Un-business card", which is a business card with fake data (even errors in the name).

So whenever someone I don't like ask me to work with them I still seem kind to give them a business card, but at the same time they will not bother me anymore.

But as I said, it intentional!
