For the "Crack porn" it's basically Macker's way of saying "revenge porn", especially when the context is given.

he's basically saying it's okay to draw porn of someone without their consent. 

He says "adults don't have to consent for me to publicly have sexual fantasies of them", hinting something really sinister about his morale(What will he do to a minor's consent, then?). Adding how he's drawing porn of me, clearly out of spite, and defending/justifying it, just further enforces my disdain for him as a "person".

And "fursonas are not real people". A fursona may not exist by itself, but it's still used to represent someone online, someone that DOES exist. Fursonas are designed to represent an actual person online, in art, or other forms of media, without showing the person's face. A fursona DOES represent someone.
