I think what MariusArmand is trying to ask is why would you add spells like that to the site that aren't real but dislikes when younger kids pretend to be one of these mythical creatures.
I think it is as someone said below to bring traffic to the site.
But when your older common sense tells you that doing some silly little ritual wont turn you into a mythical creature. I don't really agree with those spells being listed here, but to each his own.
Maybe I'll start a topic where everyone can list magick spells that personally worked for them later. Who knows, it may help a few people! :)
