>>96550845This is what's called spec work and it's a legitimately shitty thing to do and is textbook taking advantage of your fanbase. Fun fact: People were railing against Nijisanji for doing spec work when Selen was trying to hold an outfit contest and Niji didn't want to allow her to pay anyone and would maintain ownership of designs submitted even if they didn't win the contest. Everyone unanimously agreed this was bad, including /vt/.
Of course since this is Hololive people will go out of their way to defend it.
