How does extra punctuation translate into Spanish?

Question

If there are more than one punctuation marks at the end of a sentence, does the beginning mark change, too? For example, if on a flyer it said "FREE SALE!!!" would the Spanish equivalent be "¡¡¡VENTA LIBRE!!!" or only one at the beginning?

Answer 1

One expert says

To indicate an extremely strong exclamation, it is acceptable to use
two or three exclamation points (not more): ¡¡¡Idiota!!! (Idiot!)

But in practice, people do all kinds of things.
