Thanks for the question slyro, we use the stripe payment gateway on this site. Unfortunately paypal does not allow this type of content to be purchased via it's portal which is why we chose stripe (stripe does have a category for us) of course people do use paypal on a more personal level for selling this type of content but we are unable to use it on a site of this size. You payment details go directly (and securely - notice the secure padlock on your browser) to stripe after filling out the payment form and we in-fact don't get any of your details other than a name. Funnily enough if you paid via paypal it would disclose your full details. I can understand your concern and I do thank you for the question but I can assure you that this is site is both extremely secure and above board.
