The thing is that they do have a point.
It is unbelivably rude to use others' models without their permission, but the way they decided to address the issue just yells "I'm a literal who and I need attention"
Which I'm sure is the case for 9 out of 10 people involved in this shitstorm
Even if I agreed with this (I don't, Cyberlive is fucking dead and nobody even uses those models anymore AFAIK) the way to go about this is to send a PRIVATE MESSAGE to Lumi herself about it. Even if your intentions are bad, it's still the best thing to do, because if she says no or backtalks you, THEN you can get pissy on twitter with receipts and a generic 'i did this in good faith blah blah' disclaimer. This was the cuntiest, womanish way to do things and they deserve all the shit that gets shovelled back over their fence for it.
