Potato... Moon? That's almost a cool name. Either that or I have bad taste when I'm sleep deprived and its late at night.
And I think she's using Japanese copyright laws (ah, Japan, where sale of Dojinshi for profit is totally legal) or just plain crazy. Her defense is less based on entitlement and more on what appears to be a really loose, really really loose, sense of 'public domain'. According to her it has to do with how famous the characters used are, not how old the copyright is. Though she (and her mouthpiece) seem to lack the smarts to actually know the phrase "public domain".
And that's just Potato Moon, I haven't even looked at the other guy yet as his name is less interesting.
