There arw issues with this idea.
Firstly comes the fact that with legitimate work, results will vary. Magic is not like an item you purchase online, made consistently at a manufacturing plant. Everyone will have a somewhat different experience.
Secondly, what is or is not possible or valid as a work can be found with research, and often just by reading the post.
Not to mention there are plentyof people lurking this site who believe in the quite simply unrealistic. Such people would highly rate just about anything.
