I have asked admin about the availability of this feature previously.
I would like to see the cams being available on an "ask and allow" basis....
that is, that if someone wants to view your cam, they need to request to view, so that the person on cam has control of who is seeing them.
It's not right that people have been blocked for whatever reason, but they can still watch your cam & comment publicly.
Thanks Greedy for bringing up this issue here.
