So last night I requested:
>Supergirl being disciplined with Wonder Woman's trunks stuffed in her mouth.

Almost immediatly I got a reply that said:
>Anon. Anon. For the love of fuck, Anon. You know how these threads started? "Draw Scrooge McDuck as an Orange Lantern." That sort of thing. Cute, sometimes funny, occasionally sexy stuff that other fans might like to see.Your request screams "go fucking commission it." That's not "boy I bet other fans want to see this," that's just pure fetish.

Don't know when these threads started getting these wierd commentaries on requests, but thanks for the epiphany. I just did it myself.
