Regarding commercial selling of DeepVocal voicebanks

Reading the terms of conditions of DeepVocal, it turns out that in order to sell DeepVocal voicebanks, it is required to obtain permission from the developer, Boxstar, themselves in order to do so. However, their twitter account is no longer active and I am not able to access Weibo. Does anyone know how to contact Boxstar regarding this topic?

Boxstar’s bilibili:

Deepvocal QQ group 367077631

QQ is giving me issues regarding signing up due to my phone number being “suspicious” so I don’t think I can join the group anytime soon. I do have a WeChat account if that helps…
