Anyone found to be recording a model without permission get banned from Chaturbate.

Unfortunately theres no way to prevent users recording at this present time.

Chaturbate do offer a Free DMCA service on your behalf (removal or block of the content), you can email them support@chaturbate.com with the links to the content including your username.

You can also add a free DMCA badge to your profile which can be found from this website: http://www.dmca.com/

One piece of advice that can be given is that public shows are mostly recorded, but Password / Ticket shows & Private shows can be a better way of protecting yourself.
