Since the guy seems to have deleted his post, I still have a screenshot of it and I'll put a response.
We get that the ideas are terrible. Yes, they are terrible. But you're taking people who are simply providing some customer service to thank you for favouriting/watching their works, and dragging their name through the mud by including their name and icon in your "joke."
This time the perfectly innocent artist was attacked so much they shut down their FA page until the witch hunt blows over.
Seriously, you can make the joke, but either use your own picture/icon, create one that is clearly a joke and photoshop it in, or just censor the name/picture. Otherwise people are going to take it as fact and attack people.
