While it's not exposure in the traditional sense of the word, in that there's no "secret" being given away that spoils a magic effect, it's still not good form. The reason being, Pandora is an intellectual property, in the same way a book or a film is. Maybe not legally, but certainly ethically. In the same way that distributing a pirated film steals from the creators, distributing or watching an unauthorised tutorial of a flourish takes money away from the inventor. Basically, don't do it. If you want something that costs money, you have to pay said money.
