I want to know the Do's and Don'ts of the zipzapUTAUs. What's okay and what's not?

That's a great question.

Take a look at the Terms of Use - if not, here's a quick summary of the more important bits of the TOU:

• Use them like you would any other UTAUloid.

• For commercial use: Alright if you are a well-known vsynth producer, small business, or someone who makes high quality figurines and plush as long as we're notified via email. No soulless problematic corporations, please.

• No redistribution (unless they're discontinued - put them on archive.org if they do)

• Do not use the zipzapUTAU voices for your own VB. 

• No politics or hate. (for the former: ALL kinds of politics, except fictional, are forbidden. The latter is just as forbidden.)

• No fetish art (and NSFW of Marula, Stan, Stella, Pam, Sunny, Kira, or possibly Tara)

• Do not use the zipzapUTAUs with generative AI in any way, shape, or form. SynthV AI tuning is perfectly fine.

• There is a blacklist of songs, most of them are ones that make the people of ZipZap uncomfortable- alongside a list of blacklisted users.
