Will have this confirmed with Support.  Please keep watching this for updated answer.

EDIT

Support have stated that if a model changes the price of Fan Club membership the price that the previous members signed up to stays the same.

On last checking with support, there are no rules against this.  But will check again to confirm and will update this answer.

Sorry no, this is not allowed, this is classed as breaking copyright.

There is no restriction for broadcasting on other webcam sites simultaneously.

The only rule regarding other webcam sites is that you are NOT allowed to advertise other webcam sites.

Drinking alcohol on cam is NOT allowed, there was a mix up between Support & Admins.

You need to contact support@chaturbate.com they are the only ones that can fix this issue for you.  They are a little behind on emails so please give them time.

If you’re having issues with sending Private Messages on each time you broadcast, please try switching to another browser.  If this continues email support@chaturbate.com with all the details including which browsers you have tried.

Broadcasting simultaneously on other sites is not against the rules.

But advertising / promoting other sites IS against the rules.
