Thanks a lot for the explanations, I didn't know the 
autocomplete="off" tag.

Nevertheless, the problem persists and seems to be even deeper, 
indeed, my site is hosted on Heroku and I can see what a user who 
is on another machine has written (behavior I just found out). 
Fortunately, this little site is only for entertainment purposes, 
but it is a behavior that seems quite vicious.

If you want to access the code, it is on [this 
repository](https://github.com/noc-lang/playground) (it is just a 
playground for the language of a friend).
