It's not even my product so I'm not trying to sell it, just inform people about it since it is a great product and theres a store on this website that sells tricks along with other various things magic related.

It's spam because you are posting links to something you want to sell. That's a no-no. This is a Learning Site, not a market place.

Can I ask how sharing an extremely useful tool which helps magicians learn new magic, supposedly what this site is all about (learnmagictricks.org i mean its in the URL..), is spam?

That's Strike Two. One more time, and I'm gonna ban ya. Don't post spam.
