Crazy Credit Declines

Couple of years ago I had no problem adding fake memoriam card's to this series, I know real ones aren't allowed because they go in the 'Thanks' section but these are made up ones, I explained that in the box and added screenshot of said card to show the ridiculous nature of it, but every time they are declined. I mean their names are 'Sick Little Freak', 'Smelina from Arizona' etc, obviously end credit jokes. I guess I'll not bother in future, but tell me if I'm doing something wrong?
