ok so my sister recorded a voicebank today and created an utau wiki page for it and she put that her utau was a vipperloid isnt that like copy right or something ? it has a really good design like professional look to it and it sounds nice buts a cv bank she said that it was supposed to be a troll anyway but she decided to make a good bank instead ? sorry if its confusing so can it be considered a vipperloid since its a troll like the others ?
