That's a shame; a lot of people often comment on A_B posts saying they'll not commission an artist when they never had the intent anyway, but I think Acorn's work is really cute and was considering it. But as someone who has waited years for art and not gotten anything before, this really rubs me the wrong way, so commissioning her is a definite no-go now.
And altering other people's work, for pay no less, that's exceptionally trashy.
