hi,
to be honest, when i realized that i made a mistake by writing "adversite" instead of "advertise", i had already published the content and i was too lazy to fix it
but, then i thought that, as remi mentioned, it might be accepted as a word trick, just like "automagically". i am not a native english speaker but i believe that "adversite" is something acceptable
in fact, i want to learn what native speakers think about that
