This is a public site where just about anyone can publish a spell in the spellbook. So the spellbook has good spells and bad spells. Just like a poetry site will have good poems and bad poems. You shouldn't be picking up a spell if you don't know how to practise magick, and if you are knowledgeable concerning magick, you'll be able to detect which spells are good and which ones are bad.
As for the forum, we have those new to magick and those that have practised for many many years. We have ranks to distinguish who has proven shown their knowledge. Rank however does not always express experience. Those who are ranked low could be completely green or could be highly experienced but not outspoken.
The fortunes area is just for fun. You don't wear a mood ring to seriously indicate your mood do you? It's for entertainment purposes, "cool", etc.
So no, this site is not "fake" but this site isn't 100% educational. If you want purely educational, go to http://www.sacred-magick.com/ or http://www.esotericarchives.com/
