learntomod.comは安全ですか？

I don't trust this site because, first of all, it wants you to pay 30 dollars per year for a service that nobody knows about, although the book: "Minecraft Modding for Kids" tells you about it. I checked the reviews for the book on Amazon, and there were lots of one star reviews, all of which were people who signed up for learntomod.com and got conned. Basically, it will take your money for a "one year subscription" and cancel it after a few months. Others just said that the service was terrible. It asks for your email address, which seems to suggest that they will send spam, or will sell your information. Stay away. This site is aimed at kids who like Minecraft and get sucked into things like this. Very, very bad.
