You are allowed to include other performers in your Club/feed, as long as you have previously age verified your co-performer(s) and have clear proof of consent per our Terms of Services Section 6.5.
If you wish to publish content featuring another Creator, make sure to toggle the option "Yes" on your post to declare your co-performer. You will need to keep your co-performer's ID and signed release form, as we may ask for a copy of the documentation. The work title on the release form can be a general "My Club content" statement.
To verify a co-performer that is not currently a verified Creator on MV, simply keep a copy of their valid government issued photo ID, along with a signed co-model release form as it may be requested at any time as per 2257 regulations.
You can find our blank release form here.
