Ah... I think you're good in these kinds of situations, so I'll ask for some advice. I was livestreaming today and this guy kept bugging me for a request - I finally accepted but said I'll only draw it if I am motivated. He asked for his Gardevoir and Charizard kissing, and I refused because I have no idea how to draw a long muzzled creature kissing a flat faced one. Then he kept making passive aggressive comments and augh, it was so awkward. What would you do in this kind of situation?

I would have banned him.  If someone wants to be an asshole in my stream, they can leave.  If they won’t leave, I will make them.  I want my stream to be an enjoyable environment for everyone who wants it to be an enjoyable environment for everyone……
