I'm putting an X on this one, I highly doubt gamersupp contacted the artist, they shout him out on twitter and that's it.
If the artist was truly getting a cut from the merch, he'd have shilled it on his twitter. I know I would.
We literally just have an example of Yuniiho re-alive herself to shill zentreya's nendroid.
we literally have footage of her randomly walks into a streamer room. Did ya think that was staged?
This paragon of intelligence also meet up with her groomers/mods/regular chatters, you know the thing ky0resu tries to sell, she does it for free.
It wasn't being careful that left her yab free, it's being reckless as fuck and by some god's miracles she isn't involved in shit.
Or she might already have and it's burried in layers of NDAs.
Even the fact that she did this for 3 whole years without the original artist knowing is a miracle in itself.
