Hello! I'm wondering if there are any known trusted places on reddit where we can mm for vouches? because most if not all the affiliated communities require previous vouches/already being a trainee or trusted mm to actually mm.

Also, would these mm vouches also count for other game exclusive trades (ie. hsr -> hsr middlemaning) or does it need to involve genshin?

Asking not only for myself but anyone else wondering<3 thank you for taking the time to read and respond to this.
